I believe this movie was made in the 1950's,early 1960's. All I rememberis a man and a woman were walking towards her father's Laboratory, he is a Scientist, and the man picks up something from the ground. They take it to the Laboratory, and place it on a table. The next day, it has grown. It looks like a little Monster. They put it in a Cage and the next day, it broke out of the cage and is much bigger. They keep on trying to keep it in a cage, and each day it growns bigger and bigger. That is all I remember. Do not remember who was in it. This has been bugging me for years and years. Anybody that could help me, I would greatly appreciate it. Even if you just point me in the right direction, that would be of tremendous help. Thanking one and all in advance.
