This movie's title, 'Between Heaven and Hell', is taken from an expression that means purgatory. They say war is hell, but in this context, the film's title refers to that place which is in a limbo zone that exists before it.
When studio Twentieth Century-Fox bought the rights to the Francis Gwaltney novel 'The Day the Century Ended', they contracted The Twilight Zone television-playwright and Philippines war veteran Rod Serling to write the film script. In World War II, Serling was a member of the 511th Parachute Infantry Regiment of the 11th Airborne Division. However, Serling's draft script was too long and was rejected. Other writers were then assigned script duties. Serling does not receive a writer's billing in this film's credits and as such it is not known the extent to which his work ended up in the final shooting script. In an interview, Serling once told of his involvement on this movie: "My first screen job was at Fox on a war flick called 'Between Heaven and Hell'. I turned in a script that would have run for nine hours on the screen. As I recall, it was over five hundred pages. I didn't know what the hell I was doing. They just said ''ere'' fifteen hundred bucks a week --write!" So I wrote. They eventually took the thing away from me and handed it over to six other writers, but I lay claim to the fact that my version had some wonderful moments in it. In nine hours of script, by God, there has to be a couple of wonderful moments!"
