<P> On a potential sequel, Norton said, "The whole thing was to envision it in multiple parts . We left a lot out on purpose . (The Incredible Hulk is) definitely intended as chapter one ." Leterrier made the film's final shot of Banner ambiguous; the thought being if there is a sequel, it would mean Banner finally masters control over his anger; if there is not a sequel, the shot indicates instead that he becomes a menace in The Avengers . Leterrier had also intended for a scene in the credits showing Blonsky, human once more, imprisoned and chained in a box . The character of Samuel Sterns, played by Tim Blake Nelson, was introduced to set him up as a villain in a possible future film, where he would become the Leader . Aaron Sims, the lead designer on The Incredible Hulk, also took time to work on concepts for the Leader . Nelson is "signed on" to reprise the role . Ty Burrell wants to portray the superpowered Doc Samson faithfully to the comics . </P> <P> Leterrier and Roth were originally contracted to return . Leterrier also stated Norton was not signed on, but in October 2008, Hurd stated that Norton was contracted to reprise the role . The film had outgrossed its predecessor and Universal indicated interest in a sequel, though Leterrier believed a sequel would not be made because of the film's box office return . Feige said the film met Marvel's expectations and that Hulk would return, but after the crossover . Hurd was not concerned that a sequel may not be produced until at least 2012, citing the positive reception to the film and having produced the Terminator series, the second and third film of which had a 12 - year gap . Tim Roth confirmed that Marvel had signed him for three more films . Leterrier, after having previously said he did not want to direct a sequel, said in late 2009 he had changed his mind and was now amenable . </P> <P> Mark Ruffalo began his role as Banner / Hulk in The Avengers, after Feige said he chose not to bring back Norton . In October 2014, Norton claimed he chose never to play Hulk again because he "wanted more diversity" with his career, and did not want to be associated with only one character . In April 2012, despite Ruffalo being on board to play the Hulk in the sequel, Feige confirmed to Collider that Marvel had no plans at that time to film another Hulk film . In a Q&A session, Feige and Ruffalo confirmed that discussions are underway to produce another Hulk film due to the positive audience response to Ruffalo's performance in The Avengers . In September 2012, Feige, while exploring all possible story options for a sequel film, including a film based on the "Planet Hulk" and "World War Hulk" storylines, stated, "everything (in terms of stories from the comics) is on the table . Do I think Hulk can carry a movie and be as entertaining as he was in Avengers? I do believe that . I do believe he absolutely could . We certainly are not even going to attempt that until Avengers 2 . So there's a lot of time to think about it ." </P> <P> In June 2014, Ruffalo said he believed the studio might be considering doing a new standalone Hulk film, saying, "I think they are, for the first time, entertaining the idea of it . When we did The Avengers it was basically' No!', and now there is some consideration for it . But there's still nothing definitive, not even a skeletal version of what it would be ." In July, Feige stated that the studio was not considering a "Planet Hulk" film at that time, due to wanting to feature Ruffalo's Banner in the film . However, he did not rule out a story that saw the Hulk and Banner end up in space and explained why a solo Hulk film did not occur in Phase Two of the MCU by saying, "After the first Avengers, Iron Man had his own movie, Thor had his own movie, Captain America had his own movie, and Widow and Fury were in The Winter Soldier . So it was really about, frankly, saving somebody so that the only place you could get Hulk between Avengers movies is the next Avengers movie, so (director Joss Whedon) could continue to play with that in (Avengers: Age of Ultron). Where we go after that, we'll see ." In October 2014, again on a solo film, Feige said, "We'll see . We'd love to do it, we'd love to find the place to put it, but right now, Hulk will be appearing, with his friends, in their (Phase Three) films ." </P>
