About Clyde
Manis was the trained orangutan that played Clyde, Clint Eastwood's orangutan sidekick from the 1978 box office hit Every Which Way But Loose. Its 1980 sequel, Any Which Way You Can (1980), did not feature Manis, as he had grown too much between productions. The orangutan that played Clyde in the second film died of a cerebral hemorrhage shortly after the film wrapped.
Manis returned to working with his trainers' act in Las Vegas.
