Other mistake: When Jaws breaks the glass in the control room, it shatters and flies everywhere, but the water doesn't even move or give any indication of flooding the compartment.

Jaws 3-D (1983)
1 other mistake - chronological order
Directed by: Joe Alves
Starring: Dennis Quaid, Louis Gossett Jr., Lea Thompson, Bess Armstrong, Simon MacCorkindale
Factual error: When the shark swims towards the glass, it doesn't move its tail. Sharks have to swing their tail in order to swim. There is no way this shark could be moving.
Mike Brody: White sharks are dangerous. I know 'em. My father, my brother, myself. They're murders.
Trivia: As originally envisioned, this film was going to be a parody titled "Jaws 3, People 0," as it was felt that a third film wouldn't necessarily work. The producers of the first two films brought in writers from National Lampoon to write the script and it almost went into production, but the studio shut them down at the last minute. "Jaws" producer David Brown maintained till his death that "Jaws 3, People 0" would have been much more interesting and entertaining than "Jaws 3-D" turned out to be.





Answer: You are correct that he never directed another movie because Jaws 3-D underperformed financially and was a critical failure. Alves' directing style was particularly panned. As a further humiliation, Alves was nominated as 'worst director' for the 1983 Golden Raspberry Awards.
