Tropic Thunder

A team of actors are working on a big budget vietnam war film.  The film is in trouble and things are made worse when the actor's egos collide.  Then things go horribly wrong.

Robert Downey Jr was the highlight of the film.  He cracked me up a lot.  He plays an Australian actor playing a black character to large comedic effect.  

There was mild violence and some bad language.  I would recommend this rental.
