10 Worst Practical Effects In Movie History

The original shark prop for the first Jaws movie, nicknamed Bruce, was infamously buggy and ineffective. But Steven Spielberg and production designer Joe Alves worked around that, leaned into the fact that the prop couldn't be shown a whole lot, and the result is one of the scariest movie monsters of all time.

Jaws 4: The Revenge does not share in this ingenuity.

The tricks the movie borrows from the original, by movie 4, lack the same punch. Not helped by the fact that the shark itself looks naff when it does show up. Bruce wasn't the best prop in the world due to, you know, all the sinking, and needed people like Spielberg and Alves to make it sing, but it was still a pretty good prop in its own right.

The shark for Jaws 4, by comparison,  looks completely atrocious, made worse by amateur filmmaking that takes techniques from the original without really understanding it.

This film, and this terrible, terrible shark prop, were the last death knell of the Jaws franchise - and for good reason.
