21 Jump Street

(2012) ITV, 10.45pm

This comedy take on a dopey 1980s TV show is much better than it had any right to be. Jonah Hill and Channing Tatum (above) are on hilarious form as a pair of fresh-faced cops who are sent on an undercover mission in a high school, only to find things have changed since their student days. ★★★★☆
