London: Emma Thompson threatened to quit her upcoming movie "Brideshead Revisited" after she found that the film's producers ordered her co-star Hayley Atwell to lose weight.

Contactmusic.com reports that Thompson was very angry when it was revealed that Atwell was instructed to lose some weight before shooting the movie. She demanded that producers accept Atwell's size or she would resign.

Atwell said: "I went round to Thompson's one night and she was getting very angry that I wasn't eating all the food she was giving me. I told her why and she hit the roof."
