Three Amigos!
Three Western stars (Martin Short, Steve Martin, Chevy Chase) from Hollywood silent films go to Mexico for what they assume will be a publicity appearance, and find they've actually been summoned to fight a local bandit. John Landis directed this 1986 comedy with self-conscious artifice, and it's hard to get into his self-congratulatory joke. Even the three main stars, brilliant comics all, can't sustain anything funny in it.
