Sam Rockwell is The Sitter…

Sam Rockwell will reportedly star in upcoming comedy The Sitter.

The picture follows a college drop-out- played by Jonah HIll – who is asked to babysit three mischievous children as a favour to his mother.

However, when he brings the kids along to buy drugs from Rockwell’s dealer in an attempt to impress a girl (Ari Graynor), the deal goes wrong and he ends up being chased around New York with the three youngsters in tow.

Rockwell will star alongside Curb Your Enthusiasm’s J. B. Smoove, who has also been cast as a drug dealer.

Pineapple Express’s David Gordon Green will helm the picture.
