Mark Wahlberg has revealed that he would like to replace Robert Downey Jr. as Tony Stark in the next 'Iron Man' sequel.
The 'Ted' star told Yahoo! that he is eager to make superhero films, but fears he may not be considered for that kind of role, Metro.co.uk reported.
The 42-year-old actor also added that he was once in talks to play Batman's sidekick, Robin.
