Every Which Way But Loose (1978)

Philo Beddoe (Clint Eastwood) is an easy-going trucker and a great fist-fighter. With two friends, Orville (Geoffrey Lewis), who promotes prize-fights for him, and Clyde (Manis the Orangutan), the orangutan he won on a bet, he roams the San Fernando Valley in search of cold beer, country music, and the occasional punch-up. But he is floored by country and western singer Lynn Halsey-Taylor (Sondra Locke), who gives him the slip when she realizes he’s getting too serious. Phil, Clyde, and Orville set off in pursuit, pestered by bikers.
