Frogs (1972)
1 revealing mistake
Directed by: George McCowan
Starring: Sam Elliott, Ray Milland, Adam Roarke, Joan Van Ark
Continuity mistake: Grover's eyes are closed when he's rolled over by Pickett, then his right one's open a shot later.
Trivia: When Jason dies at the end of the film, it is not Ray Milland you see but a double. This is due to the fact that Milland quit the film three days early due to his intense hatred of the production.
