Goofs in this movie
1. The baby is called Billy by the mom. Then later the police chief says "she" was only 10 months old.
2. The fat Italian starts yelling "Jack" when he is alone in the sea but the man he was referring to was called "Don".
3. Shelley Winters gets her son and his friend mixed up when she is talking on the radio. Her son is called Tommy. But at first she starts saying "Jamie, Jamie don't tease your mother."
One of the goofs listed isn't a goof because the man feeding the killer whale was Will Gleason he was wearing a white t-shirt and there were two killer whales in the pool. You can see in a wide shot him holding a fish out to the killer whale.
