Scarlett Johansson thinks Avengers: Age of Ultron will be more complex and cerebral than it's 2012 predecessor.
Johansson will reprise her role as the Black Widow and she told film website AlloCine: "Joss Whedon, who is coming back for Avengers 2, has got his finger prints all over that project, certainly just as much as he did with Avengers, if not even more.
"He's in a place now where most directors would be extremely burdened by the task of having to top the last one. But for some reason, I think the universe is working in the right way for him.
"Joss seems extremely focussed and he's in some ways less jaded. He really is in a good place to start this movie."
She continued, "He's crafted an even more complex and cerebral story this time around while still giving the fans those superhero elements that they love, the little Easter eggs, the explosions and the surprises, the little wink to the audience. He's got a very dry sense of humour as a person and as a writer."
Johansson, who is winning huge acclaim for her role in arthouse sci-fi film Under The Skin, feels that fans won't be disappointed by the sequel saying, "The irony is not lost on him. These characters are still in a completely bizarre set of circumstances, they're totally aware of what a strange team of misfits they are.
"It's pretty exciting, I think the fans will not be disappointed, unless we mess it up, which is always a possibility."
Avengers: Age of UItron is slated for a May 2015 release.
