Yes, it's that Clint Eastwood + Orangutan film! Back in 70's and 80's, all American screen heroes had to make at least one Orangutan movie. It was the iron law of Orangutany. Burt Reynolds made the classic "Cannonball Run II" which featured an Orangutan who was a pretty good comedian opposite such veteran comedic actors like Reynolds himself and Dom DeLuise. With this film, Clint Eastwood made his first staright-out comedy, though his tough, macho on-screen persona always demonstrated a wonderful deadpan sense of humour.
