According to The L.A Times British actress and recent Golden Globe nominee Emily Blunt has been offered the role of Peggy, Steve Rogers’ love interest, in The First Avenger: Captain America. But she may turn it down.
Marvel wanted Blunt for Black Widow in Iron Man 2 but 20th Century Fox still had her under contract to make another film with them from when she signed for The Devil Wears Prada. As a result Blunt had to pull out and was replaced by Scarlett Johansson in the role.
The L.A Times say that Blunt is close to signing on to other projects and will turn down Marvel’s offer. I’m not sure how they know that, but they speculate that she may be interested in other roles that are potentially more rewarding as an actress than simply playing someone’s girlfriend in a big superhero blockbuster. After all, in these types of films all the focus is on the hero and the lead female is usually played by a young actress who looks good on posters, but she is really only there to be ‘the love interest’. There are a few exceptions, but in most cases the characters are pretty one-dimensional.
If Blunt turns down Captain America then that will leave Kiera Knightly and newcomer Alice Eve (who will be seen in Sex and the City 2). There may be other actresses in the running also, but those are the ones that have been reported. Both are British, as is Blunt, so Marvel are obviously looking for an English lady to cling to the arm of Chris Evans.
Whoever lands the role will be joining Hugo Weaving, Evans, and Sebastian Stan, along with director Joe Johnston.
