Natalie Dormer had a tough time writing film with fiance

Actress Natalie Dormer says she and fiance Anthony Byrne may be totally in love, but it was tough for them to work together. The couple have collaborated on the script for the upcoming indie thriller 'In Darkness', and the 34-year-old actress said it was not as easy as she thought it would be, reported People magazine. "It's tough! I don't know if you've ever been in a writing room but I wouldn't recommend it with your other half," Dormer said. However, the former 'Game of Thrones' star is excited about the idea of starring in a movie she also wrote for the first time. "I'm very excited about it because I've never done anything that I've written before. It was a very interesting process - we were trying to write real interesting characters, both male and female.
