I need help finding a movie title
In the film, a pair of ex-lovers are sent overseas during wartime to perform a theatrical musical production to entertain the troops, but they begin to hold auditions and subsequently cast the troops in the show as well. It is a musical, I remember that for sure. There was dancing too, so maybe Fred Astaire-Gene Kelly eras (I can't remember any of the cast members that were in it, otherwise I wouldn't need help finding it). Can anybody help me? Please?
