Scarlett Johansson says Avengers Assemble fans can expect 'unbelievable excitement' from the new movie.
Johansson reprises the role of Black Widow, a character that we saw for the first time in Iron Man 2, in the Joss Whedon directed movie.
She was on the red carpet at the LA premiere of the movie earlier this week and she admits that she feels greater part of the Marvel family second time around.
Johansson joins an all star cast of Robert Downey Jr, Chris Evans, Mark Ruffalo, Chris Hemsworth and Jeremy Renner as the heroes are called upon to save the world.
The stars of the movie and the director were out in force in LA to help promote the movie, which will really kick off the blockbuster summer.
Avengers Assemble is released 26th April
