In the intro for The Sitter trailer, Jonah Hill promises the filthiest, R-rated babysitting movie ever – and it also looks like he’s been on a bit of diet since he shot the movie. In the film he play Noah, who’s been suspended from college and gets coaxed into babysitting the kids next door. As always with this sort of flick, he is completely unprepared for the wild night ahead of him. So if you like swearing kids, or indeed swearing at kids, then click below to take a look a the red band trailer for The Sitter. It’s due for UK release on January 27th, 2012.
