Matt Damon’s unhinged performance of “Scotty Doesn’t Know” is the most prominent thing I remember about 2004’s EuroTrip , as he belts out a punk-rock song about cuckolding poor Scotty. Bradley Cooper appearing as a charming little halfling with a fetish for burly barbarian women remains one of the funniest scenes in Dungeons & Dragons: Honor Among Thieves . And who can forget Bill Murray appearing as himself posing as one of the undead in Zombieland so he can golf in peace?
Damon, Cooper, and Murray are no strangers to comedy; so it comes as no surprise that they’d delight in taking these small roles for the sake of a good bit. But the most iconic surprise celebrity cameo of all time came in 2008, thanks largely to the fact that a satirical comedy put an always-serious A-list action star in a bald cap and fat suit, with layers and layers of body hair that extended all the way to his knuckles.

Each of them is uniquely terrible and a worse version of recognizable movie star archetypes.
After novice director Damien Cockburn (Steve Coogan) loses control of all these big personalities, he drops the entire cast into the jungle, hoping that hidden cameras and staged explosions might lead to better performances. Everyone is quickly put in serious danger without realizing they’re no longer making a movie.
What follows is an escalating series of chaotic, violent events that includes severed limbs, drug withdrawal, explosive diarrhea, accidental gunfire, and movie stars who can’t recognize a genuine crisis even when it literally explodes in their faces. Oh, and a young child gets hurled from a bridge into a river at one point — in case you weren’t sure whether Tropic Thunder was downright irreverent or not.
