I've seen this movie at least twice but can't recollect the name. A man goes to what I believe is Paris, meets some friends and goes to a local club for drinks and a floor show. I'm sure this part is near the beginning of the movie.
I think the man is a Kirk Douglas or a William Holden type. Strong leading man who is well known. I seem to remember him in a military uniform.
The floor show is of a dancer and a musician. The dancer does a routine where a glass of water or champagne is placed on her and she does all these acrobatic routines and doesn't spill a drop.
I can't remember anything else about the film other than that dance routine.
