In Tropic Thunder (2008), some actors, their director, and a member of the crew are filming a movie about the daring rescue of a captured American soldier during the Vietnam War. They accidentally move off-set and out of Vietnam, into Laos --the territory of a heroin-trafficking drug cartel. Except they still think they are filming a movie!
They are:
1. Tugg Speedman (Ben Spiller), an action-adventure star who tried to move into drama with Simple Jack, about a mentally-disabled farm boy. It bombed, but it happens to be the drug cartel's favorite movie.
2. Rick Peck (Matthew McConaughey, left), his agent and gay-subtext best friend. When Tugg is captured by the drug cartel, he rushes to the rescue.
3. Jeff Portnoy (Jack Black), famous for a series of movies about a family who farts. If you like chub, he's got an extended scene tied up in his underwear (which displays quite a bulge).
