Thor is a 2011 American superhero film based on the Marvel Comics character Thor. Produced by Marvel Studios and distributed by Paramount Pictures, it is the fourth film in the Marvel Cinematic Universe (MCU). It was directed by Kenneth Branagh, written by the writing team of Ashley Edward Miller and Zack Stentz along with Don Payne, and stars Chris Hemsworth as the title character alongside Natalie Portman, Tom Hiddleston, Stellan Skarsgård, Kat Dennings, Clark Gregg, Colm Feore, Ray Stevenson, Idris Elba, Jaimie Alexander, Rene Russo, and Anthony Hopkins. After reigniting a dormant war, Thor is banished from Asgard to Earth, stripped of his powers and his hammer Mjölnir. As his brother Loki (Hiddleston) plots to take the Asgardian throne, Thor must prove himself worthy.
Sam Raimi first developed the concept of a film adaptation based on Thor in 1991, but soon abandoned the project, leaving it in "development hell" for several years. During this time, the rights were picked up by various film studios until Marvel signed Mark Protosevich to develop the project in 2006, and planned to finance and release it through Paramount. Matthew Vaughn was assigned to direct the film for a tentative 2010 release. However, after Vaughn was released from his holding deal in 2008, Branagh was approached and the film's release was rescheduled to 2011. The main characters were cast in 2009, and principal photography took place in California and New Mexico from January to May 2010. The film was converted to 3D in post-production.
Thor premiered in Sydney on April 17, 2011, and was released in the United States on May 6, as part of Phase One of the MCU. It received generally positive reviews from critics and was a financial success, earning $449.3 million worldwide. Three sequels have been released: Thor: The Dark World (2013), Thor: Ragnarok (2017), and Thor: Love and Thunder (2022).
Plot
In 965 AD, Odin, king of Asgard, wages war against the Frost Giants of Jotunheim and their leader Laufey, to prevent them from conquering the Nine Realms, starting with Earth. The Asgardians defeat the Frost Giants and seize the source of their power, the Casket of Ancient Winters.
In the present, Odin's son Thor prepares to ascend to the throne of Asgard but is interrupted when Frost Giants, secretly allowed in by his brother Loki, attempt to retrieve the Casket. Against Odin's order, Thor travels to Jotunheim to confront Laufey, accompanied by Loki, childhood friend Sif and the Warriors Three: Volstagg, Fandral, and Hogun. A battle ensues until Odin intervenes to save the Asgardians, destroying the fragile truce between the two races. As punishment for Thor's arrogance, Odin deems his son unworthy and strips his powers before exiling him to Earth as a mortal, accompanied by his hammer Mjölnir, now protected by an enchantment that allows only the worthy to wield it.
Thor lands in New Mexico, where astrophysicist Dr. Jane Foster, her assistant Darcy Lewis, and mentor Dr. Erik Selvig find him. The local populace discovers Mjölnir, which S.H.I.E.L.D. agent Phil Coulson soon commandeers before forcibly acquiring Foster's data about the wormhole that delivered Thor to Earth. Having learned about Mjölnir's nearby location, Thor seeks to retrieve it from the facility that S.H.I.E.L.D. has constructed and tries to lift it, but is unable to do so and is captured. With Selvig's help, he is freed and resigns himself to exile on Earth as he develops a romance with Foster.
Loki discovers that he is Laufey's biological son, adopted by Odin after the war ended. Loki confronts Odin, who wearily falls into the deep "Odinsleep" to recover his strength. Loki takes the throne in Odin's stead and offers Laufey the chance to kill Odin and retrieve the Casket. Sif and the Warriors Three, unhappy with Loki's rule, attempt to return Thor from exile, convincing Heimdall, gatekeeper of the Bifröst—the means of traveling between worlds—to allow them passage to Earth. Aware and suspicious of their plan, Loki sends the Destroyer, a seemingly indestructible automaton, to pursue them and kill Thor. The warriors find Thor, but the Destroyer attacks and overpowers them, prompting Thor to offer himself instead. Struck by the Destroyer and near death, Thor proves himself worthy to wield Mjölnir. The hammer returns to him, restoring his powers and enabling him to defeat the Destroyer. Thor and Jane kiss each other goodbye before he leaves with his fellow Asgardians to confront Loki.
In Asgard, Loki betrays and kills Laufey. Thor arrives, and Loki reveals his plan to destroy Jotunheim with the Bifröst Bridge. Thor fights Loki before destroying the Bifröst Bridge to stop Loki's plan. Odin awakens and prevents the brothers from falling into the abyss created in the wake of the bridge's destruction; when Odin rejects Loki's pleas for approval, Loki allows himself to fall into the abyss. Thor makes amends with Odin, admitting he is not ready to be king and longs to see Jane. Meanwhile, on Earth, Foster and her team search for a way to open a portal to Asgard.
In a post-credits scene, Selvig is taken to a S.H.I.E.L.D. facility, where Nick Fury opens a briefcase and asks him to study a mysterious cube-shaped object, which Fury says may hold untold power. An invisible Loki, who survived his fall and arrived on Earth, secretly prompts Selvig to agree.
Cast
Chris Hemsworth as Thor:The crown prince of Asgard, based on the Norse mythological deity of the same name. Director Kenneth Branagh and Marvel Studios chief Kevin Feige chose Hemsworth after a back-and-forth process in which the 25-year-old actor was initially dropped from consideration and then given a second chance to read for the part. Hemsworth stated that he gained for the role by eating non-stop and revealed that "It wasn't until Thor that I started lifting weights, it was all pretty new to me." After taking an initial costume fitting, Hemsworth returned three weeks later to find it did not fit because of the mass he had cultivated in that time span. At that point, he shifted away from eating a lot of calories and training to a kettlebell workout that would maintain his muscle mass rather than continuing to add to it. Regarding his take on the character, Hemsworth said, "We just kept trying to humanize it all, and keep it very real. Look into all the research about the comic books that we could, but also bring it back to 'Who is this guy as a person, and what's his relationship with people in the individual scenes? About approaching Thor's fighting style, he remarked, "First, we looked at the comic books and the posturing, the way [Thor] moves and fights, and a lot of his power seems to be drawn up through the ground. We talked about boxers, you know, Mike Tyson, very low to the ground and big open chest and big shoulder swings and very sort of brutal but graceful at the same time, and then as we shot stuff things became easier." Hemsworth also adopted a British accent for the role, stating that it suited the film’s Shakespearean and mythological tone, and added that an Australian accent would have made the character resemble "Crocodile Dundee". Dakota Goyo portrays a young Thor. Natalie Portman as Jane Foster:A scientist and Thor's love interest. Marvel Studios stated in an announcement that the character was updated from the comics' initial portrayal for the feature adaptation. When asked why she took the role, Portman replied, "I just thought it sounded like a weird idea because Kenneth Branagh's directing it, so I was just like, 'Kenneth Branagh doing Thor is super-weird, I've gotta do it. Portman stated that she really wanted to do a big effects film that emphasized character, and getting to do it with Branagh was a new way of approaching it, relative to Star Wars. Regarding her preparation for the role Portman remarked, "I signed on to do it before there was a script. And Ken, who's amazing, who is so incredible, was like, 'You can really help create this character'. I got to read all of these biographies of female scientists like Rosalind Franklin who actually discovered the DNA double helix but didn't get the credit for it. The struggles they had and the way that they thought – I was like, 'What a great opportunity, in a very big movie that is going to be seen by a lot of people, to have a woman as a scientist'. She's a very serious scientist. Because in the comic she's a nurse and now they made her an astrophysicist. Really, I know it sounds silly, but it is those little things that makes girls think it's possible. It doesn't give them a [role] model of 'Oh, I just have to dress cute in movies'".
Tom Hiddleston as Loki:Thor's adoptive brother and nemesis, based on the deity of the same name. Hiddleston was chosen after previously working with Branagh on Ivanov and Wallander. Initially, Hiddleston auditioned to play Thor but Branagh decided his talent would be better harnessed playing Loki. Hiddleston stated that the character was "a comic book version of Edmund in King Lear, but nastier." Hiddleston had to keep a strict diet before the start of filming because Branagh wanted "Loki to have a lean and hungry look, like Cassius in Julius Caesar. Physically, he can't be posing as Thor". Hiddleston looked at Peter O'Toole as inspiration for Loki as well, explaining, "Interestingly enough, [Kenneth Branagh] said to look at Peter O'Toole in two specific films, The Lion in Winter and Lawrence of Arabia. What's interesting about ... his performance [as King Henry] is you see how damaged he is. There's a rawness [to his performance]; it's almost as if he's living with a layer of skin peeled away. He's grandiose and teary and, in a moment, by turns hilarious and then terrifying. What we wanted was that emotional volatility. It's a different acting style, it's not quite the same thing, but it's fascinating to go back and watch an actor as great as O'Toole head for those great high hills". Ted Allpress portrays a young Loki. Stellan Skarsgård as Erik Selvig:A scientist doing research in New Mexico who encounters Thor. Skarsgård stated that he was not initially familiar with the comic book version of Thor. As to why he took the part, Skarsgård remarked, I "chose Thor because of [director] Kenneth Branagh. The script was nice and we got to rehearse and talk to the writers and do some collaborating in the process to make it fit us. So I had a very happy time on it. What I always try to do is immediately do something I just haven't done so I get variation in my life. I've made about 90 films and if I did the same thing over and over again I would be bored by now. I try to pick different films, I go and do those big ones and having done that I can usually afford to go and do some really small obscure films and experiment a little". Kat Dennings as Darcy Lewis:A political science major who is Jane Foster's intern. Dennings described her character as Foster's "little helper gnome". Dennings stated that her role was expanded during the rehearsal process. Dennings explained, "She's kind of like a cute, clueless, little puppy or maybe a hamster. There wasn't much on the page for the Darcy role to begin with and I didn't even see a script before I took the job so I didn't really know who Darcy was at first. But she really evolved—she's so much fun now even. She's very Scooby-Doo if that makes sense. She's always three steps behind and reacting to what's happening with these great expressions ... She gets things wrong and doesn't care." Clark Gregg as Phil Coulson: A S.H.I.E.L.D. agent. Gregg reprises his role from the Iron Man films.
