Have you heard of it? Directed by John Sturges 1968, with Rock Hudson and Ernest Borgnine.
Most of the movie happens on a submarine, but before the MGM Lion roars, the film is preceded with a musical overture, accompanied by the big all caps word OVERTURE written across the screen. Maybe this created undue excitement and high expectations. The well designed stage sets do create a good sense of the close confinements inside a submarine. So Rock Hudson gets in this submarine with a lot of goodlooking guys in army and navy outfits, they even get wet, but at no time do they ever take off their shirts, and we never get a chance to see any good backside shots of Hudson. Instead, the plot involves someone supposedly sabotaging the submarine because it is trying to rescue some people or something. But then there is an INTERMISSION, with Intermission Music, and then, there is an ENTR'ACTE, with Music for that, too. I began to get excited again. But not only was there no skin in this movie there weren't any musical numbers, either. I don't know what to make of it. Rock Hudson is weird.
