He portrayed Matt Boyd in the 2010 remake of "Piranha" which was a nod to his Matt Hooper character. Incidentally, the Piranha film series is in itself is a spoof of Jaws.
The release of this film marks the 50th anniversary of the release of Jaws (1975), which was Richard Dreyfuss' first acting performance in a shark film.
Tagline is a direct copy of the one from Alien (1979).
