It’s been a few years since we’ve heard from Jason Reitman (whose last couple of films weren’t particularly well-received), but he’s back this year with two new movies, one of which finds him reteaming with screenwriter Diablo Cody. The duo obviously had their biggest success with Juno, but their 2011 collaboration Young Adult was a bit darker and more mature. Their latest film is called Tully and seems to be heading down a similar path with Charlize Theron also starring once again. She plays an exhausted mother of three who is gifted a night nanny (Mackenzie Davis) by her brother (Mark Duplass) to help out. The first trailer keeps things somewhat mysterious but the movie seems to be about the “unique bond” that they form. Tully hits theatres on April 20th; check out the first trailer after the jump and see what you think.
