It is difficult to remember a time before the Marvel Cinematic Universe was the undisputed king of the box office, but in 2008, the studio was still finding its footing. Following the surprise success of Iron Man, Marvel Studios released The Incredible Hulk, a reboot intended to wash away the mixed reception of Ang Leeโs 2003 film. While the movie was flawed and only achieved moderate commercial success, it was widely considered a step in the right direction for the Green Goliath. Much of this praise was directed at Edward Norton, whose intense portrayal of Bruce Banner was hailed by fans as the definitive live-action version of the character. However, when the time came for the Avengers to finally assemble in 2012, Norton was dropped from the roster, and Mark Ruffalo stepped in to fill the purple pants.

The decision to recast a lead actor in a burgeoning franchise is rarely taken lightly, and the split between Norton and Marvel Studios was anything but amicable. The primary catalyst for the change was a fundamental clash of creative visions. Norton, known for his hands-on approach to filmmaking, reportedly rewrote large portions of The Incredible Hulk script during production, pushing for a more introspective tone similar to Christopher Nolanโs The Dark Knight. Marvel Studios President Kevin Feige, however, was building a cinematic universe that required actors to be team players willing to serve a larger, interconnected narrative.
The tension boiled over in the lead-up to The Avengers, culminating in a now-infamous press release from Feige. The executive stated that the decision to part ways with Norton was “rooted in the need for an actor who embodies the creativity and collaborative spirit of our other talented cast members.” This remark suggested that Nortonโs desire for creative control was incompatible with the studioโs “all for one” mentality. Nortonโs camp fired back, calling the statement “offensive” and “unprofessional,” but the damage was done. Marvel wanted a Bruce Banner who could blend seamlessly into an ensemble, not a star who demanded final cut.
Mark Ruffalo’s Hulk Is Great, If Underused

When Mark Ruffalo made his debut in The Avengers, skepticism was high, but it evaporated the moment he delivered his secret: “I’m always angry.” Ruffaloโs performance captured a nervous energy that contrasted perfectly with the ego of Tony Stark and the stoicism of Steve Rogers. Audiences immediately embraced this new iteration, and Ruffalo effectively stole the show in the third act. Since that breakout performance, he has become a staple of the MCU, appearing in eight live-action films and the Disney+ series She-Hulk: Attorney at Law. His longevity in the role is undeniable, and he is even scheduled to return in the upcoming Spider-Man: Brand New Day. Yet, despite his frequent appearances, Ruffalo is a main Avenger who feels perpetually relegated to a supporting role.
The reason for this narrative sideline lies in the complicated distribution rights of the character. While Marvel Studios owns the production rights to the Hulk, Universal Pictures retains the distribution rights for any solo Hulk film. This legal gridlock means that if Disney were to make a standalone movie, it would have to share the profits and control with a rival studio. Consequently, Marvel has been forced to weave Bruce Bannerโs character development into other heroes’ movies.
The celebrated “Planet Hulk” storyline was condensed into a subplot for Thor: Ragnarok, and Bannerโs transformation into “Smart Hulk” occurred entirely off-screen during the time jump in Avengers: Endgame. This lack of a solo vehicle has robbed Ruffalo of the chance to explore the character’s psyche with the depth that Norton once envisioned. Key emotional milestones, such as his relationship with Natasha Romanoff (Scarlett Johansson) or his reconciliation with the beast within, often feel rushed or unearned because they happen in the margins of someone elseโs story. While Ruffalo has done an admirable job with the screen time he is given, Norton remains the only actor to have a solo Hulk movie in the MCU.
The Incredible Hulk and The Avengers are currently available to stream on Disney+.
