I saw this movie when it was re-released as a supporting feature at a cinema here in Melbourne about 1951. Don't remember much about it, except the scene where the hero (Hope) loses control of a tank and runs it into the side of the colonel's Cadillac limo (it might have been a Chrysler) but the audience was appalled, as I was, because luxury cars like this were rarely seen here in those years. It wasn't faked either, as I recall. Can someone advise what the car was? I'm compiling a list of cars used in the movies. Apart from that I thought it was a quite passable comedy and I'm hoping it might come up on late-nite TV sometime as they have occasionally shown other Paramount movies of the era. TT.
