Scarlett Johansson And Gwyneth Paltrow Different Action: Hollywood studio bosses have come up with an ingenious solution to the on-set rivalry between actresses Scarlett Johansson and Gwyneth Paltrow – separating them. I revealed how the pair clashed on the set of Iron Man 2 after Scarlett, 25, was drafted in to play the femme fatale Russian spy character Black Widow.

At 37, Gwyneth, who plays Iron Man’s feisty PA Pepper Potts, was not impressed when her younger rival received more attention in the publicity campaign and made her displeasure known to film bosses. Now I hear producers are planning to give Scarlett her own role in a break-out movie and are also hoping to land British star Emily Blunt to play the villain in the next Iron Man instalment. ‘The plan is to cast Scarlett as the Black Widow in a spin-off film with Robert Downey Jnr called The Avengers,’ says a source. ‘They are desperate to have Emily as the villain in the next Iron Man film and will continue to have Gwyneth playing Pepper, though she won’t feature in The Avengers.’
