Escape from the Planet of the Apes
by Paul Dehn, directed by Don Taylor
Among the original Apes movies, only this one had true time
travel; the others involved only relativistic time dilation, which
(as even Dr. Milo knows) is technically not time travel. But in this one, Milo,
Cornelius, and Zira are blown back to the time of the original astronauts (given the
violence of the explosion, we’re going to call it a time rift)
and are persecuted in a 70s made-for-TV manner.
