Mark Ruffalo: Avengers Sequel Will Be Darker

Mark Ruffalo has suggested that The Avengers: Age Of Ultron will be "a little bit darker" than the previous movie in the franchise.

And the actor, who plays Bruce Banner/The Hulk, told MTV News that he is confident fans won't be disappointed by the follow-up to 2012's The Avengers.

"I would say that it's better, it's cooler, it's more awesomer," Ruffalo joked.

"It's a little bit darker, but also really has Joss Whedon's incredibly witty and sly sense of humour."

He also reassured Hulk fans that his character would still have a meaty role, saying he "gets to do such great stuff" in the new movie.

Ruffalo has previously expressed his uncertainty over whether or not a Hulk solo movie is likely to happen.
