The only redeeming thing about this movie is Robert Downey Jr.'s performance. His black character was so unbelievably stupid, I laughed despite myself. The rest of the movie is painful. And there was so much hype about Tom Cruise playing a fat comic role, but alas, it's the same old Cruise acting like an asshole - except he's fat and bald. Everyone screams in this movie, the whole time as if Stiller was on cocaine when he wrote it and the actors did a few rails too before each take. The lines in this movie are exceptionally stupid, contrived, and the comedy is way over cooked. None of the gags were funny because you could see the punchlines coming from miles away. The opening scene is too long, and so is the blown off hands gag. All the jokes are begging for a laugh like a homeless bum pleading for a quarter. Tropic Thunder is a true stinker.
