This is a musical - sorta. It portrays the adventures of a Broadway actor and songwriter who wants to serve his country - Over There - but is too old to be enlisted in the army. So he finds his own way of going about it.
It's really a fun film to watch, but in 2005 maybe more for the weirdish anthropology than for anything else. In the introduction the voice over talks about how "when people get too cocky and sloppy with their flag waving, some other nation will eventually come along to prove how necessary it really is to wave flags" - or something to an equally nationalistic effect. Also, the time colorite is priceless, there's a scene with some youngsters who can't even be communicated with because of their constant breaking in to jive. Also, if you're in to marching bands, this should be your choice for the evening.
