It seems like there were dozens of "Jaws" rip-offs in the late seventies. Killer Orcas, Grizzlies, and in this film, genetically modified piranha that can strip a man to the bone in minutes. This was an exploitation picture that launched the career of director Joe Dante. It has only a little of the sideways humor that characterizes his best films, but it does try to keep the audience engaged with frequent piranha victims every few minutes.
The formula is a clear set of beats stolen from "Jaws". We start with a titillating experience that results in death, followed up by a slow discovery of what is happening, and then a series of denials of reality by officials. One of the main differences is that the obnoxious character who is trying to dismiss the whole thing, gets a comeuppance, unlike the mayor in the shark movie.
Bradford Dillman was a seventies staple as a suspicious official or businessman, and he was in a ton of TV shows of the era. Here he plays a drunk hermit like loser, who hets turned into an action hero for no particular reason. Heather Menzies, who played one of the Von Trapp children in "The Sound of Music" and Strother Martin's daughter in Sssssss, is a bounty hunter who gets caught up in the action, and veteran horror icon Kevin McCarthy starts a long association with director Dante, playing a crazed scientist. Don't ask why there is a small lizard man walking around the laboratory in the early part of the film. It never becomes important and it is simply a loose thread.
"Piranha" is an efficient, low budget fright film. The film makers do the best they can with their resources and imaginations. Although many consider it a cult classic, it simply feels standard for the times. But of course those were my times so I loved it.
