Otto Gunther Octavius is a fictional character portrayed by Alfred Molina in Spider-Man 2 (2004) and later in the Marvel Cinematic Universe (MCU) film Spider-Man: No Way Home (2021), based on the Marvel Comics character of the same name. Octavius is introduced in Spider-Man 2, whose research into fusion power with his wife Rosalie (portrayed by Donna Murphy) is being sponsored by Oscorp's genetic and scientific research division, headed by Harry Osborn.

When Octavius' fusion reactor experiment using tritium becomes unstable, resulting in Rosalie's death, the harness of powerful robotic tentacle arms equipped with artificial intelligence (AI) which he was using to safely handle the materials is fused to his body, frying the inhibitor chip keeping the arms from controlling his nervous system. After ending up in the hospital and massacring the surgeons attempting to saw them off, the arms' AI begin influencing his mind and they manipulate him to steal funds in order to attempt the experiment again, over the course of which crime spree the Daily Bugle dubs him Doctor Octopus, or "Doc Ock" for short, regarding him as New York's second effective supervillain. Along the way, he comes into conflict with Spider-Man, with Osborn offering to give Octavius tritium in exchange for handing Spider-Man over to him. Ultimately, as the experiment begins to destroy New York City, Spider-Man reveals himself as Peter to Octavius after damaging his arms, and inspires him to regain control of them and destroy his fusion reactor. A now redeemed Octavius sinks the fusion reactor into the East River, but sacrifices his life in the process.

A past version of the character returns in Spider-Man: No Way Home, being transported into an alternate universe (the Marvel Cinematic Universe) shortly before his redemption and death, due to a magic spell gone wrong causing a rupture in the multiverse, and ends up clashing with that universe's (MCU) Spider-Man and his allies. After the MCU Spider-Man and his closest friend, colleague and Harry's father Norman replaces his faulty inhibitor chip with a working one, Octavius regains control of his arms and his mental state like he did before his original death, and joins the MCU Spider-Man, his Spider-Man and another alternate version of Spider-Man in fighting other universe-displaced supervillains, including Norman's alter ego Green Goblin. After briefly reuniting with his version of Spider-Man, now older, Octavius is returned to a branched/alternate timeline of his universe. Molina has expressed further interest in reprising the role in the in-development Sony's Spider-Man Universe (SSU) film based on The Sinister Six.

Molina's performance as the character, considered one of the earliest portrayals of Octavius as a tragic villain, has been acclaimed by critics and audiences, resultantly the character has come to be considered one of the most iconic villains in the superhero genre.

Concept and creation

The character of Otto Octavius / Doctor Octopus first appeared in print in The Amazing Spider-Man #3 (July 1963), and was created by writer Stan Lee and artist Steve Ditko.DeFalco "1960s" in Gilbert (2008), p. 93: "Dr. Octopus shared many traits with Peter Parker. They were both shy, both interested in science, and both had trouble relating to women...Otto Octavius even looked like a grown up Peter Parker. Lee and Ditko intended Otto to be the man Peter might have become if he hadn't been raised with a sense of responsibility.The Amazing Spider-Man #3. Marvel Comics. Lee recounted: "usually in creating a villain the first thing I would think of was a name, and then I would try to think of, 'Well, now that I've got the name, who's the character going to be and what will he do?' For some reason, I thought of an octopus. I thought, 'I want to call somebody Octopus. And I want him to have a couple of extra arms just for fun'. But I had to figure out how to do that". The character soon re-appeared in The Amazing Spider-Man #11-12 and then again in #31-33, becoming a fan favorite.

Otto Octavius was originally intended to be the secondary antagonist of Spider-Man (2002), but director Sam Raimi eventually dropped the concept in favor of spending more time with Harry and Norman Osborn. Raimi decided to use Octavius as the main antagonist of Spider-Man 2 (2004) due to being both a visually interesting villain and a character who could be seen as sympathetic. In a draft written by Michael Chabon, a younger Doc Ock becomes infatuated with Mary Jane. His mechanical limbs use endorphins to counteract the pain of being attached to his body, which he enjoys. When he injures two muggers on a date, this horrifies Mary Jane and in the resulting battle with Spider-Man his tentacles are fused together, and the fusion begins to kill him. In the script, Octavius is the creator of the genetically altered spider from the first film, and gives Peter an antidote to remove his powers: this means when Octavius is dying with his tentacles, he wants to extract Spider-Man's spine to save himself. This leads to an alliance with Harry (a detail which made it into the finished film). Beforehand, Harry and the Daily Bugle put a $10 million price on Spider-Man's head, causing the city's citizens to turn against him.

Before Alfred Molina was cast in the role several actors were considered for the role, including Ed Harris, Chris Cooper (who would later portray Norman Osborn in The Amazing Spider-Man 2), and Christopher Walken; In February 2003, Molina was cast as Octavius for the film, undergoing physical training for the role. Raimi had been impressed by his performance in Frida (2002) and also felt that his large physical size was true to the comic book character. Molina was unaware that he was a strong contender for the role, only briefly discussing it. He was excited to get the role, being a big fan of Marvel Comics. Although he was not familiar with Doc Ock, Molina wanted to maintain the cruel, sardonic sense of humor the character had in the comics.

Special effects To create Doctor Octopus' mechanical tentacles, Edge FX was hired to create a corset, a metal and rubber girdle, a rubber spine and four foam rubber tentacles which were long and altogether weighed . The claws of each tentacle, which were called "death flowers", were controlled by one puppeteer sitting on a chair. Each tentacle was controlled by four people, who rehearsed every scene with Molina so that they could give a natural sense of movement as if the tentacles were moving due to Octavius' muscle movement. On set, Molina referred to his tentacles as "Larry", "Harry", "Moe" and "Flo".Mike Cotton. "Spider-Man 3." Wizard: The Comics Magazine June 2007: p. 30–31.

For Spider-Man: No Way Home (2021), Doctor Octopus' mechanical tentacles were created through CGI instead of puppetry. According to Tom Holland, Molina had to subsequently "relearn" how to act using them.

Return of the character Upon being cast as the character, Molina signed a three-movie option should the producers chose to renew his contract. Although he told them that he assumed his contract was null and void upon filming his death scene, producer Avi Arad told him to not assume that as "nobody really died" in the Marvel Universe. Molina first expressed interest in portraying the character again in The Amazing Spider-Man series. In an August 2014 interview, while promoting Love Is Strange (2014), Molina expressed his openness to return as Doctor Octopus in a film based on the Sinister Six, then-intended for a 2016 release, after the character's appearance in that film was teased at the end of The Amazing Spider-Man 2 (2014), but reflected that the filmmakers could choose to go for another actor. By September 2019, an untitled The Sinister Six film had re-entered development, Amy Pascal stating the following October that it would feature villains of Marvel Studios' Spider-Man films. By September 2021, the film was confirmed to be in active development, to be set in Sony's Spider-Man Universe.

After The Amazing Spider-Man film series was cancelled, Sony Pictures and Marvel Studios announced in February 2015 that Spider-Man would appear in the MCU, with the character appearing in an MCU film and Sony releasing a Spider-Man film co-produced by Feige and Pascal. Sony Pictures would continue to own, finance, distribute, and exercise final creative control over the Spider-Man films. "For the first few films, it was always, 'How do we do things that have never been done before?' It did not occur to us to do a new Goblin story, or to do an Oscorp story, or to do Doc Ock, or anyone that had been done before, which is why Vulture and Mysterio were really the key characters," Marvel Studios president Kevin Feige reflected. Feige conceded "you can't get better than Alfred Molina as Doc Ock" and furthered that if they "were ever going to bring Doc Ock back, it would have to be Alfred Molina and in early development on this third Homecoming movie, we realized that thanks to the MCU, there was a way to do that."

In December 2020, it was reported that Molina would reprise his role as the character in Spider-Man: No Way Home (2021), which is intended to be set in the Marvel Cinematic Universe. In April 2021, Molina confirmed his involvement with film, calling it "wonderful" to reprise his role. He also revealed that Octavius's story in the film would pick up mere moments after the events of Spider-Man 2. Molina was digitally de-aged in the film to resemble how he appeared in 2004, despite his concerns about his fighting style not looking realistic due to his age in a similar way to Robert De Niro's character in The Irishman (2019).

Fictional character biography Before Spider-Man 2 Dr. Otto Octavius is known as a nuclear physicist, a close friend of Dr. Curt Connors, and a scientific idol of Peter Parker. His work is funded by Oscorp, run by Norman Osborn. Octavius worked primarily at home, with his wife and lab assistant, Rosalie Octavius. They both fell in love because they were passionate and philosophical in their fields of physics and literature.

Becoming Doctor Octopus

Two years later (2004), Octavius meets Peter Parker through Harry Osborn, Norman Osborn's son and Harry's best friend. He recognizes Parker as the "brilliant but lazy" student of Dr. Curt Connors. Octavius takes a liking to Parker because of his intelligence and shared interests. He encourages Parker's intellect and advises Parker to use it for good.

Octavius later demonstrates his work for Oscorp investors: a nuclear fusion reactor, a 'perpetual sun' created to provide clean and affordable energy. Octavius also invented tools for working with the reactor: four bionic tentacle-like arms that are impervious to heat and magnetism. A metal harness attaches the arms to his torso, and the arms are connected to and controlled by his brain through needles injected into his spinal cord. To protect him from being controlled by the tentacles' AI, he created an inhibitor chip connected to his cerebellum. However, during the experiment, the fusion reactor starts to attract metallic objects inside of its core. Despite Harry demanding Octavius to shut it off, he refuses, thinking that he can control it.
