Scarlett Johansson has revealed that she was nervous about being the 'new kid on the block' on Iron man 2.
The actress takes on the role of the Black Widow in the movie and stars alongside Robert Downey Jr and Gwyneth Paltrow.
Speaking at the premiere of the movie the actress said: At first I thought I might feel like the new kid on the block, but I was so warmly welcomed by Robert and Gwyneth and Jon - I felt like I was inducted into the brotherhood.
The actress also went on to joke about the tough training regime she put herself through to get ready for the movie.
"I'm now a master mixed martial artist, but I don't want to let people know that because I'm afraid that they're going to constantly challenge me to a fight or a dual.
"[I did] lots of training, strength, stunt, every imaginable possible training you can do I did to be able to do the stunt work and I guess I'll see if it pays off tonight," the actress told reporters.
"She is a woman on a mission and that's what makes her more exciting, that mysterious nature, that duplicitous side."
Iron Man 2 is released 30th April.
