Is this the movie where a diver runs out of air?

There are two movies that come to mind the first is After the Sunset (2004), Woody Harrelson gets his air turned off and has to be rescued. The second is a very obscure movie called Deadly Jaws (1974) which revolves around a search for treasure and toward the end of the movie a woman diver has to hold off coming out of a ship because of some sharks that are outside and she is running low on air and she waits to long and starts to pass out. She is wearing a full facemask and she is rescued just in time. It's funny I came across your post because I just watched it the night before off a grindhouse movie collection that it is on. You can possible find it at Best Buy for about 30 dollars or so, thats where I found my copy. It is called Gindhouse movie collection number 2 it has about 20 movies and it's right for the price. I hope that helps you. After the Sunset is readily available at any rental place and you could possible find it at Walmart pretty cheaply as well
