I'm trying to find the title of a film about a man who swam with sharks.
He had a special necklace that allowed him to swim with the sharks and not be attacked. If he didn't have the necklace on they would attack - which is how the film ends (I think) with him being thrown in the tank without the necklace. Also, a key point is that this tank with the sharks is below his house - he has a trap door in his kitchen/living room that goes straight into water. My brother and I seem to remember him living in a cabin in the woods (not sure how that would work... ). I imagine it's a film from the 70s or early 80s.
