Justin and Jen are writing a movie script together

Justin Theroux and Jennifer Aniston are said to be writing a script together – and hope it’s going to be the next big comedy movie to hit our screens.

The Iron Man 2 writer has apparently convinced his fiancée to pen a comedy with him, despite the fact she doesn’t have much experience on the other side of the camera.

The couple are said to have worked out a story idea and a list of characters for the movie.

Jen and Justin- who have been engaged for almost two years – have yet to walk down the aisle, although Jennifer recently hinted it could happen in 2015.

She said,”There is a lot of work that is happening this year. I’m working and finishing tweaking little bits and pieces of my house [in Los Angeles].

“But then its going to stop, and we’re just going to live there. 2015 will be nesting, 100 per cent, I’ve got to take a break.”
