In the third of the 'Apes' series, Cornelius (Roddy McDowall) and Zira (Kim Hunter), along with a third chimpanzee, Milo (Sal Mineo), manage to escape from Earth 3955 before it blows up.They land on Earth 1973. Milo is killed by a non-speaking gorilla. (Mineo himself was killed five years later, though not by a gorilla. This was his last movie.)
The tables are turned as Cornelius and Zira are befriended by kindly scientists Bradford Dillman and Natalie Trundy. Cynical genius Eric Braeden (now on The Young and the Restless) wants to kill the apes, who are expecting a baby. Helpful circus owner Ricardo Montalban takes them in and adopts their baby, who goes on to star in the next installment.Passable entertainment, but it's no fun watching the likable, witty Cornelius and Zira become hairy martyrs. With a rinky-dink score by Jerry Goldsmith and a confusing explanation of infinite regression. Watch for M. Emmet Walsh as the military aide with the oranges.
