French actress Marion Cotillard is hitting the big screen once again, this time as the star of the new film “Allied,” a historic romantic thriller set in the 1940’s during World War II. Cotillard plays the role of a French resistance fighter working with a Canadian spy, played by her co-star Brad Pitt.

Brad Pitt may be single again (in fact, the trailer for Allied dropped on the same day that Angelina Jolie announced her divorce from Pitt) but in an interview on the Late Show with Stephen Colbert, Cotillard explained to Colbert that filming the many sex scenes that are in the new movie was not as sexy as it sounds. Apparently, Pitt and Cotillard are too seasoned and professional to get squeamish about filming sex scenes.

Cotillard also dished about her character’s role as a potential double agent in the film, as well as what she likes and doesn’t like about America (too much air conditioning, apparently) and about her pregnancy.
