A movie where astronauts find a casino spaceship that the gamblers died in when it spun out of control. It’s a B&W film. The effects were pretty good since I believe it was made in the 50’s or 60’s.
I think the casino was saucer shaped, and I seem to remember cards and chips floating in zero g. A few corpses. Well preserved. Nothing gruesome.
The astronauts discuss it and determined it spun out of control and depressurized.
