Channing smartened up in a grey suit with a black tie and shoes, getting about as adventurous as you can with a suit (well, apart from the powder blue number in American Pie) by choosing a shirt with a plain white collar and pinstriped body.
Oh yeah. He went there.
The film's released on March 16th, and sees Channing and Jonah play undercover police officers who have to pose as high school students to crack a case.
Which means we get to see him in uniform. Sweet.
