Editing Spider-Man (2002 film) (section)

===Visual effects===
[[John Dykstra]] was hired as the film's visual effects supervisor in May 2000.<ref>{{cite web |last=Chitwood |first=Scott |date=May 10, 2000 |title=Dykstra to animate Spider-Man |url=http://movies.ign.com/articles/034/034448p1.html |access-date=January 22, 2007 |website=[[IGN]] |archive-date=January 19, 2012 |archive-url=https://web.archive.org/web/20120119175529/http://movies.ign.com/articles/034/034448p1.html |url-status=live }}</ref><ref>{{cite magazine | url=https://www.rollingstone.com/tv-movies/tv-movie-features/sam-raimi-multiverse-of-madness-doctor-strange-interview-spider-man-1344342/ | title=From 'Spider-Man' to 'Doctor Strange': How Sam Raimi Conquered the Superhero Multiverse (Again) | magazine=[[Rolling Stone]] | date=April 30, 2022 }}</ref> He convinced Raimi to use [[computer-generated imagery]] (CGI) for many of the stunts that were physically impossible. Raimi had used more traditional special effects in his previous films.<ref name="HBO" /> Raimi worked hard to plan all the sequences of Spider-Man swinging from buildings, which he described as, "ballet in the sky." The complexity of such sequences meant the budget rose from an initially planned $70{{spaces}}million to around $100{{spaces}}million.<ref name="empire" /> Shots were made more complicated because of the main characters' individual color schemes, so Spider-Man and the Green Goblin had to be shot separately for effects shots: Spider-Man was shot in front of a [[greenscreen]], while the Goblin was shot against bluescreen. Shooting them together would have resulted in one character being erased from a shot.<ref name="hughes" /><ref>{{cite web |last=Susman |first=Gary |date=May 2, 2017 |title=24 Things You Never Knew About Sam Raimi's 'Spider-Man' |url=https://www.moviefone.com/news/spider-man-sam-raimi-tobey-maguire-facts/ |access-date=July 12, 2024 |website=Moviefone}}</ref><ref>{{cite web | url=https://www.mentalfloss.com/article/73988/why-are-green-screens-green | title=Why Are Green Screens Green? | date=January 21, 2016 }}</ref>

Dykstra said the biggest difficulty of creating Spider-Man was that as the character was masked, it immediately lost a lot of characterization. Without the context of eyes or mouth, a lot of body language had to be put in so that there would be emotional content. Raimi wanted to convey the essence of Spider-Man as being, "the transition that occurs between him being a young man going through puberty and being a superhero." Dykstra said his crew of animators had never reached such a level of sophistication to give subtle hints of still making Spider-Man feel like a human being.<ref>{{Cite news |last=Zonkel |first=Phillip |date=March 20, 2003 |title=Spinning 'Spider-Man's' Visual Effects Web – Former CSULB Student John Dykstra Is Credited with a Great Deal of Computer-Generated Movie Magic |work=[[Press-Telegram (Long Beach)|Press-Telegram]] |location=Long Beach, California}}</ref> When two studio executives were shown shots of the computer generated character, they believed it was actually Maguire performing stunts.<ref name="hughes" /> In addition, Dykstra's crew had to composite areas of New York City and replaced every car in shots with digital models. Raimi did not want it to feel entirely like animation, so none of the shots were 100% computer-generated.<ref>{{cite web |last=Worley |first=Rob |date=March 6, 2002 |title=Comics 2 Film |url=http://www.comicbookresources.com/columns/index.cgi?column=comics2film&article=1259 |access-date=April 29, 2007 |website=[[Comic Book Resources]] |archive-date=October 12, 2007 |archive-url=https://web.archive.org/web/20071012135923/http://comicbookresources.com/columns/index.cgi?column=comics2film&article=1259 |url-status=live }}</ref>
