Then in 1978, Every Which Way But Loose took that formula and added Dirty Harry and an orangutan. It couldn't miss. The movie was a light comedy, but it was an enormous hit. Even 40 years later, Every Which Way But Loose is on the list of the top 200 highest grossing films of all time. You might want to learn more about it.
