Continuity mistake: When Mike goes down to the ocean to hug his mother, she turns with the ocean at her left hand. When it cuts to them hugging the ocean is at her right hand. (00:11:50)
Continuity mistake: When Hoagie lets Thea steer the plane, Carla is sitting beside Mike in the background. When it cuts Carla suddenly has her arm raised, resting on the seat. (00:17:45)
Continuity mistake: When Michael is standing by the window and Carla is lying in bed, Carla rests her head on her arm. When it cuts Carla is suddenly lying down in bed. (00:35:55)
Continuity mistake: When Mike, Jake and Hoagie are in the plane searching for Ellen, when looking out the window they are flying over land. When it cuts they are suddenly over the ocean and when it cuts again they're over land. (01:08:50)
Continuity mistake: Michael Caine is knocked overboard into the water, but manages to climb back into the boat - when he reaches the deck, his clothes are perfectly dry.
Continuity mistake: Throughout the entire film, Ellen Brody's hair changes back and forth from blonde to white.
Continuity mistake: When Mike sees through the binoculars that his mom is walking with hoagie sandwich, you can see she is wearing white shoes. However, when it cuts to the next shot she is barefoot.
Continuity mistake: In one of the final scenes in which the shark is attacking, the colour of the water is not consistent in the background. In one scene it is light blue, and in the other it is much darker blue.
Continuity mistake: The transmitter device that Jake attaches to the shark is missing between shots during the entire movie.
Continuity mistake: When Ellen is on the boat, and sees the shark coming towards her, the distance between her and the shark does not look very far. When it cuts to Mike, Jake and Hogie in the plane, from their view the distance between the boat and shark looks much greater, about 60-70 metres. Also, only about five seconds later, the shark jumps out of the water and strikes the boat, the shark could not have swam that distance in such a short time.
Continuity mistake: When Jake and the crew struggle against the shark, all the shots where Hoagie's body is in the back have no continuity with his position in the next shot of him.
Continuity mistake: When Jake is about to be eaten his shirt swaps from dark pink to light pink between shots.
Suggested correction: She doesn't put her foot in its mouth. She instinctively tries to kick it or she's just unlucky with where she moves her foot.

She put her leg in the shark's mouth. It's too obvious even without slow motion.
