Cop Out is an interesting movie for Kevin Smith for three reasons. It's the first time he's directed a studio picture. It's the first film he's made with somebody's else's script. And it's the first time he's directed a major movie star in the lead role.

Much though we love Mr Smith's work, though, you have to say this trailer isn't too promising. Warner Bros has made no shortage of cop movies, and the idea of putting Bruce Willis front and centre of a action comedy of this ilk is a fine one. From the trailer though - and this is appreciating it's just a trailer - the focus seems to be very much on Tracy Morgan instead. And he's just not too funny here for our money.

Willis, of course, has the potential to lift the film, and Smith is a very good director of comedy. Right now though, we just think this trailer to Cop Out is doing the film not too many favours. Let us know what you think in the comments below.

The film is released in February...
