Norton and director Louis Leterrier also clashed with producers over their desired 135-minute cut of The Incredible Hulk, a dispute that spilled out into public. Norton submitted his own draft within a month, as stipulated by his contract with Marvel Studios, and continued to revise the script well into production according to co-star Tim Roth, who played Emil Blonsky, there were daily rewrites. With a filmography that included Fight Club, The Italian Job and The Illusionist, Norton negotiated a deal not only to star in The Incredible Hulk but also be the uncredited screenwriter (Zak Penn, who wrote the first draft, was credited by the Writers Guild of America as the solo writer). However, the film's production was tumultuous.

NOTE: Updated on June 9, 2021, to reflect Mark Ruffalo's involvement in Disney+'s She-Hulk series, and to elaborate upon the circumstances surrounding Edward Norton's departure from the MCU. Here's everything we know about why Marvel Studios replaced Edward Norton with Mark Ruffalo. However, one of the biggest ways The Incredible Hulk differs from the other films is that it's the only one to have recast its title character for subsequent appearances, with Mark Ruffalo replacing original actor Edward Norton, beginning with 2012's The Avengers. While the 2008 film is still canon, important supporting characters like Betty Ross (Liv Tyler) have not reappeared in the MCU, and the end-credits tease of Samuel Sterns (Tim Blake Nelson) transforming into the classic villain The Leader was never realized. The Incredible Hulkis something of an outlier in the Marvel Cinematic Universe.
