Clint Eastwood is seen here hanging out with the orangutan, Clyde, from the movie Every Which Way But Loose, which is an absolutely insane movie. It is a comedy about a motorcycle riding Eastwood who hangs out with an orangutan and gets into fights. It spawned a sequel called Any Which Way You Can which is just as beloved.
The movie is a lot of fun, but also very strange. Multiple times throughout the movie, it'll break into the titular theme song “Every Which way but Loose.” They really wanted to get their money's worth out of that song. Clyde the orangutan later moved to an orangutan haven to live out the rest of his life in peace. At the end of the day, an orangutan just wants to chill, not worry about being a Hollywood actor.
