Where to watch The Butterfly Effect (2004)

Trivia & production notes

• The script originated as The Blackouts, written by Eric Bress and J. Mackye Gruber in 1998, and featured a scene with a six-year-old character shooting police officers that their manager deemed too dark for mainstream audiences.
• The original script ending depicted the protagonist strangling himself inside his mother's womb, which so disturbed producer Chris Bender that he signed the writers the next day.
• Every studio that received the screenplay rejected it due to its dark subject matter combined with the writers' insistence on directing the film themselves.
• After impressing New Line Cinema executive Richard Brener, Bress and Gruber were hired to write Final Destination 2, and only received the green light to direct The Butterfly Effect once that film went into production.
• Directors Bress and Gruber initially wanted an unknown actor for the lead role, but when their candidate suddenly became famous, they lost contact with them and eventually cast Ashton Kutcher on the studio's suggestion.
• Ashton Kutcher served as an executive producer on the film and studied dissociative disorders to prepare for his role as Evan Treborn.
• Kutcher worked closely with child actor John Patrick Amedori, who played 13-year-old Evan, to ensure their performances remained consistent across the film.
• The studio commissioned three alternative endings despite resistance from the directors and cinematographer, after initially getting cold feet about the originally planned bleak conclusion.
• During editing, a scene meant to be darkly comedic where Evan wakes up as a bilateral amputee fell flat because test audiences were too invested in the story to find it funny.
• The theatrical ending was chosen over the filmmakers' preferred version after test audiences strongly responded to the scene where Evan returns to sever ties with Kayleigh, causing Bress and Gruber to initially feel betrayed by the studio's decision.
