The made-for-TV Invasion of Johnson County is based on a dark chapter in the history of Wyoming. As settlers pour in, a cartel of Wyoming cattle barons raise a private army to wipe the "interlopers" off the face of the Earth. Bostonian Bill Bixby teams with good ol' boy Bo Hopkins in warding off the villains. If the story for this TV movie strikes a familiar chord, it is because the same historical incident was used as the basis for Michael Cimino's 1980 megabomb Heaven's Gate. The principal differences: Heaven's Gate lasted three dreary hours, while Invasion of Johnson County zipped along at 100 rousing minutes; and while it didn't set fires in the ratings, at least Johnson County didn't destroy United Artists.
