The story is mostly flashback on flashback. The basic story is of Capt. John Yossarian (Alan Arkin), World War II bombardier, who wants to get out of the war. However it gets real complicated with many characters that are players by a bevy of character actors. There is plenty of subtle comedy mixed with some scenes that can make you sick.
A lot of what looks like disjointed and irrelevant scenes with becomes one cohesive story by the end. Even the frontal nudity scene fits. If you like this sort of film you should watch "Jacob's Latter."
With all the effort and great filming this film still has no exceptional or socially meaningful message. Luckily the film is complete and we can understand what is being cut out of TV versions.
My favorite part was the part where when Yossarian first sees Luciana (Olimpia Carlisi) in white walking by and they play "Also sprach Zarathustra" Written by Richard Strauss
