Justin Theroux Will Swear To God

With Will Ferrell and Steve Carell

Will Ferrell and Steve Carell are already set to reunite for Anchorman 2, and it's now confirmed that they'll be working together on a further project. They're both signed up for the Warner Bros. comedy Swear To God, which Justin Theroux will direct.

We haven't heard much about this one since late last year, when it was just a project that Ferrell might be doing. There was some suggestion that Adam McKay would direct, but those rumours were quickly scotched.

The film's suddenly arriving almost fully-formed is a surprise then, although it sounds as if it'll be thoroughly overhauled before it goes before the cameras. The original screenplay was by Due Date writers Alan Cohen and Alan Freedland, but Theroux will now be re-writing it himself. McKay will be involved as a producer, since Swear To God is a "Gary Sanchez" picture (his production company, with Ferrell). It involves Ferrell playing a narcissist who believes God is speaking to him.

Theroux previously wrote Tropic Thunder, of course, and is attached as writer and director to the developing Zoolander 2, but this will be his first gig behind the camera since his debut Dedication in 2007. He'll have plenty of time to prepare, since shooting doesn't start until next July.
