Kevin Feige claims an independent 'Hulk' movie could happen after 'The Avengers 2'.

The 'Avengers' producer claims there may be room for Mark Ruffalo portray the green character in a stand-alone movie, but only once a second film in the 'Avengers' series is complete.

He said: ''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. I don't think there's a lot that we couldn't do someday.''

Hulk plays a major role in the 'Avengers' movie but previous attempts to make a film about the character - portrayed by Eric Bana and Edward Norton - have been unsuccessful.

However, Mark has claimed recently he could not foresee a stand-alone Hulk movie.

He said: ''I think they've done it. I think they feel that they've done that. I think they don't really know where to go [with the character].''
