The first season of Smallville, an American television series developed by Alfred Gough and Miles Millar, began airing on October 16, 2001, on The WB television network. The series recounts the early adventures of Kryptonian Clark Kent as he adjusts to his developing superpowers in the fictional town of Smallville, Kansas, during the years before he becomes Superman. The first season comprises 21 episodes and concluded its initial airing on May 21, 2002. Regular cast members during season one include Tom Welling, Kristin Kreuk, Michael Rosenbaum, Eric Johnson, Sam Jones III, Allison Mack, Annette O'Toole, and John Schneider.

The season's stories focus on Martha and Jonathan Kent's (O'Toole and Schneider) attempts to help their adopted son Clark (Welling) cope with his alien origin and control his developing superhuman abilities. Clark must deal with the meteor-infected individuals that begin appearing in Smallville, his love for Lana Lang (Kreuk), and not being able to tell his two best friends, Pete Ross (Jones III) and Chloe Sullivan (Mack), about his abilities or his origins. Clark also befriends Lex Luthor (Rosenbaum) after saving Lex's life. The season also follows Lex, as he tries to assert his independence from his father, Lionel Luthor (recurring guest star John Glover).

The episodes were filmed primarily in Vancouver and post-production work took place in Los Angeles. Gough and Millar assisted the writing staff with week-to-week story development. "Villain of the week" storylines were predominant during the first season; physical effects, make-up effects, and computer generated imagery became important components as well. Limited filming schedules sometimes forced guest actors to perform physical stunts, and the series regulars were more than willing to do stunt work. Episode budgets ultimately became strictly regulated, as the show frequently ran over budget during the first half of the season. The pilot broke The WB's viewership record for a series debut, and was nominated for various awards. Although the villain of the week storylines became a concern for producers, critical reception was generally favorable, and the series was noted as having a promising start. The first season was released on DVD on September 23, 2003, and included various special features that focused on individual episodes and the series as a whole. It has also been released on home media in regions 2 and 4 in the international markets.

Production Writing Ground rules for story development were established at the outset. Part of the marketing pitch, "no flights, no tights" dictated that Clark Kent would not wear the Superman costume, nor would he fly. After initial discussion of possible storylines, a second rule decreed that Clark could never directly kill anyone. This created a dilemma since Clark would be able to defeat the "bad guys" from week to week. A solution was developed in later episodes with the introduction of the Belle Reve sanitarium; Belle Reve is a federal prison for metahumans and other supervillains in the comics.

After setting the ground rules, developers and showrunners Alfred Gough and Miles Millar conceived ideas that facilitated week-to-week story development. For example, kryptonite's role was expanded to include enhancement of the sins of the antagonist: instead of creating physical monsters, exposure to kryptonite would amplify their personal demons. This was not treated as literally in the pilot and "Metamorphosis" as it was in later episodes. In "Cool", it was "the 'cool' kid literally [becoming] cool, needing human body heat to stay alive". After several episodes, the writers developed a story that would help establish the show as more than a "villain of the week" series.Simpson, Paul, pp. 52–55 The ninth episode, "Rogue", which took longer than usual to develop due to its divergence from the standard formula, became their first "true crime story" and demonstrated that Smallville could include more than kryptonite-powered villains.

"What if" episodes were another Millar-Gough concept used to generate first season storylines. These episodes posed underlying questions about Clark. Episodes would evolve from basic questions, including: "what if someone had a crush on Lana, and acted on that obsession"; "what if someone found out Clark's secret"; "what if someone else had Clark's powers?" These three questions developed into the episodes "Metamorphosis", "Rogue", and "Leech", respectively.Simpson, Paul, pp. 64–67 "Stray", episode 16, answered the question, "what if Clark had been adopted by the wrong parents and his powers were exploited?" "X-Ray" writer Mark Verheiden and the rest of the crew realized divergent, unrelated storylines were not the best way to create episodes for Smallville. Verheiden believes "X-Ray" was the first episode that managed to bring all the side-stories together so that they affected characters other than Clark and Lana.Simpson, Paul, pp. 32–35 "As [Lex] touches one of the flowers it withers and dies, sending a cancerous wave of death rippling out across the field, laying waste to everything in its path. Suddenly, A BLOOD RED DROP falls from the deep blue sky, stains his suit. Then another falls, and another and another, until the sky is raining red. As he opens his mouth to scream, there's a flash of white".— Vision of Lex Luthor's future, as described in the script.

"Hourglass" was one of the stories included in Millar and Gough's initial pitch to the network; at the time it was referred to as "Cassandra".Simpson, Paul, pp. 40–43 "Hourglass" was the first episode to present two, distinct stories: the vengeful serial killer and the second sighted Cassandra. Two significant storylines in the same episode forced the writers to spend more time developing the episode. Cassandra's "visceral vision" (as it was referred to in the script) of Lex's future was developed into color storyboards to better illustrate to the filmmakers the "blood rain" described in the text.

When the filmmakers were dissatisfied with the initial drafts of episodes, specifically with the evolution of characters, they would rewrite events, or add scenes to re-establish the original vision. The character of Earl Jenkins (Tony Todd), intended to be a sympathetic villain, came across as "completely unlikable" in the original draft of "Jitters". The character suffers from over-exposure to kryptonite, causing massive seizures; if Jenkins happened to grab someone, they could be shaken to death. Originally, the character is first seen banging on the door of LuthorCorp and killing a security guard during one of his seizures. To present a more favorable aspect to the audience, a scene in which Earl visits his infant child was added to show that he was not a "raving maniac". Similar rewrites occurred with the characters Ryan James (Ryan Kelley) in "Stray" and Tyler Randall (Reynaldo Rosales) in "Reaper". In the original draft of "Stray", Ryan developed his telepathic abilities from exposure to kryptonite;Simpson, Paul, pp. 80–83 to emphasize the show was not always about kryptonite-infected villains, the story was revised so that Ryan had his ability from birth. The network also expressed dissatisfaction with Ryan as a murderer, so the character was rewritten to be the "nice kid". The character of Tyler shared Earl Jenkins's issue: he was not sympathetic enough in the filmmakers' eyes; intended to be an escaped prisoner, he was rewritten to be "the world's deadliest nice guy".Simpson, Paul, pp. 84–86

Filming Production was set up in Vancouver, British Columbia, Canada, because the creators were looking for a "Middle America landscape", and Vancouver was a good substitute for Kansas.Simpson, Paul, pp. 8–17 David Nutter, the director of the pilot, was given 16 days for main unit filming, twice that of the normal timeframe. Despite the extended schedule, it was still a short amount of time, and he shot the pilot primarily from storyboards created by Adrien Van Viersen.Simpson, Paul, pp. 20–23

Millar developed most of the look for Smallville with the idea that Smallville should be the epitome of "Smalltown, USA". Millar's design required existing buildings to be painted, built, and remodeled. The Kent farm is the home of the Andalini family, and their barn was used for the pilot before a new barn was built. The new barn was one of the major additions to the sets of the episode "Metamorphosis". Production designer Doug Higgins and his crew built a fully functioning, three-story barn for the Kent farm on a converted soundstage in Burnaby. For the pilot, the crew built only a loft, with a set of stairs leading up to it, inside the existing barn on the Andalinis' property.Simpson, Paul, pp. 24–27 To resemble the Andalinis' barn as closely as possible, Higgins had his crew locate 100-year-old wood to match the look of the Andalinis' barn. The episode "Hourglass" called for several scenes to take place at the White House. Instead of building their own set, the Smallville producers called John Wells, producer of the political drama television series The West Wing (1999–2006), and obtained permission to use the West Wing set to film the vision of Lex's future.

When the Smallville crew was not filming on one of the constructed sets, or on a sound stage, they were shooting on location at the surrounding Vancouver sites. During the filming of "Metamorphosis", Vancouver was holding a farmers' market, which proved beneficial to the Smallville crew, as "Metamorphosis" called for a similar event to take place in the episode. The market was on the verge of ending, so the filmmakers shot what wide-angle scenes they could at the time, and filmed a close up conversation between Whitney Fordman and Clark at the Andalini's farm, weeks after the initial market shooting. Other filming locations include Vancouver's Pacific National Exhibition and Burnaby's Swangard Stadium. The Pacific National Exhibit provided a storage silo for a scene in "Hourglass", which involved Harry Bollston (Eric Christian Olsen) attacking Martha Kent in the Kents' corn silo. "Hothead" director Greg Beeman, who had previously worked with Gough and Millar on Martial Law (1998–2000) and The Strip (1999–2000), used Swangard Stadium, as a substitution for Smallville High Stadium, for the opening football scene that took place at night.Simpson, Paul, pp. 28–31

When filming fell behind schedule, another director came in to assist the main unit director in finishing the episode. Beeman assisted director Chris Long for the two "visceral visions of the future" that appeared in the episode "Hourglass". "Jitters" was an episode with so many changes that its initial scheduling as the second episode of the season was pushed back to the eighth spot. By the time filming for "Jitters" was completed, three directors had worked on the project: Beeman, Philip Sgriccia, and Michael W. Watkins, the latter who was given sole directing credit for the episode.Simpson, Paul, pp. 48–51
