When I was a young boy, I remember watching a 1950's-era movie, probably a grade "B" western, where a man was being held captive in a small cave. The bad guy rolled a boulder in front of the cave to prevent the man from escaping.

The bad guy would look through a small opening in the rocks to talk to the man and give him food and water. After a few days the man in the cave made a bow and arrow using sticks and laces. When the bad guy peered in through the small opening, the captive man shot an arrow into his face and killed or seriously wounded the bad guy and escaped from the cave.

That's all I remember about the movie. I would like to watch it again if someone can remember the name.
