I enjoyed this darkly humorous tale in the same way I enjoy "Dr. Strangelove".
With Peter Sellers, Slim Pickens, and Sterling Hayden, there is always something new in their delivery that you pick up. The same with Kubrick and Adam's sets and cinematography...
Slim Pickens was the perfect choice for Maj. Kong; Sellers could not have pulled it off.
I understand they never told him it was a comedy.
