I remember watching a movie or tv show years ago (possibly between 1985 and 1995), that had a group of characters that were trapped in or otherwise had to navigate a maze/funhouse type scenario. At one point, they were in a large room/hall that had many many many doors, seemingly identical. I think the hall was oval or elliptical. Only one door was apparently real, though. The characters were despairing, when one of them tries to check each door in turn by knocking on it and listening for an echo to see if there was space beyond. It turned out that the “fake” exits were small closets. Despair. Then, one character decides to light a candle or match and hold it in front of each door, expecting that the REAL door will have a draft that flickers or puts out the candle. That works, and the characters are on their way.
Or, something like that. I know it may not make sense (why wouldn’t they just OPEN each door? Perhaps the makers were trying to show creative problem solving)
I think the program was animated.
Does this ring a bell for anyone?
postscript: After thinking about it, it may have taken a non-trivial amount of time to open a door. Perhaps they were all locked and the protagonists had to manually pick the lock on a door to try it? Then, the delay in individually picking dozens of doors may be significant.
