We will pose as villains to get close to the bad guys. That way, no one will suspect we're really the good guys.

The Green Hornet (2011)

Chosen by me because I like to go to the cinema a lot, plus I'm a fan of Michel Gondry.

A little too sombre to work fully as a comedy, the arguments between the two leads mean there is little in the way of chemistry or even much of a reason to care why they would want to be heroes (because they are bored is all the film really offers).
Otherwise a generally fun time with decent if not spectactular action scenes, a good actor playing an ok bad guy (his moderately interesting through line of wanting to be seen as a super villain never quite gets the pay-off it needs).
There is next to no reason why Britt Reid should think posing as a criminal is a good idea, but since the film plays him as an idiot, I guess that doesn't particularly matter.
