Mila Kunis, last seen in Book Of Eli and Date Night, has signed to star in relationship comedy Friends With Benefits. Will Gluck is directing the film.

Which is just one of several projects floating around Hollywood (Ivan Reitman is making one of the others) with the title, which will find a female head-hunter (Kunis) sick of commitment-phobic blokes.

And a male mag editor (Justin Timberlake) tired of women who try to get him into a relationship having what they think is a casual fling. But then they fall in love. And the trouble really starts.

Keith Merryman and David Newman wrote the script, and the movie should start filming in July. Whether it keeps the title might depend on when it arrives in cinemas:

We’re guessing the first to the post with the name will claim the right to use it. And make the others wash its car for a month. Metaphor: stretched to breaking point.
