The movie was another military comedy starring actor Elliott Gould who had recently starred in Robert Altman's box-office smash 'M*A*S*H' (1970). The movie's main poster even had the following tagline: "The most hilarious military farce since M*A*S*H".
The movie was theatrically released in the U.K. as 'C*A*S*H' (1975). This was to connect and cash in with the title of Gould's earlier box-office smash picture 'M*A*S*H' (1970). Interestingly, the title 'C*A*S*H' even rhymed with 'M*A*S*H'. Moreover, Gould had also recently appeared in an espionage spoof which also had an acronym title as well. This picture was called 'S*P*Y*S' (1974).
Teri Garr was first choice for playing the nurse and she was almost signed to do the film, but Elliot Gould felt he owed it to his then-girlfriend Jennifer O'Neill to push for her to get the role. O'Neill was eventually cast, but she and Gould broke up during the production.
In this military comedy, Elliot Gould plays a character named 'Frapper.' In the military comedy 'M*A*S*H', Gould played a character named 'Trapper.'
