The third and final entry in the popular time-traveling trilogy finds Marty (Michael J. Fox) heading to the Old West to help his pal Doc (Christopher Lloyd). But while Doc falls head-over-heels for a sweet schoolmarm (Mary Steenburgen), it's Marty's feud with notorious gunslinger and outlaw Buford "Mad Dog" Tannen (Thomas F. Wilson) that may prevent them from ever returning to the present. Lea Thompson co-stars, with Fox also appearing as Marty's ancestor Seamus McFly. 118 min.
