Did You Know?


When Richard Dreyfuss was interviewed about the film, he explained "I don't know anything about 'Piranha' other than the work I did on the film. I worked for two days in the middle of the desert, got my check and then left. I didn't understand 3-d in the '50s and I can't say I get it now either. I just don't see what the big deal is".

Although it is very likely that prehistoric piranha trapped in an underground lake evolving over millions of years in complete darkness would, like many deep sea creatures, have vestigial eyes, be true albinos (colorless like cave species) and have developed bio-luminescent capabilities, this would not occur without random mutations to the generic code. Unless there is distinct evolutionary pressure (competition, shortage of resources, visibility to predators, etc.), they would not necessarily evolve these changes (and vestigial structures only become as such if specific random mutations occur or there is a major energy cost to maintaining the active structure). However, things that are advantageous when unable to see would have to evolve for them to find prey, so it is realistic that the piranha developed a highly sensitive sense of smell, as is apparent from their swift attraction to blood from a significant distance. The concept that a top predator could survive for several million years purely by cannibalism without an input of external energy is false. However, they could conceivably have survived if some source of energy was available to fuel the bottom of the food chain. As the underground lake was sealed from sunlight, one possibility is an ecosystem based on geothermal energy. Such ecosystems do, in fact, exist in the benthic zones. So, in theory, at least, the piranhas could have sustained themselves as top predator of a food chain that started with geothermal micro-organisms. See more »

"Too much but not enough."
7 March 2011 | by xtian_durdenSee all my reviews

A movie that deserves every letter of its R rating. An over-the-top combination of nudity and terrifying brutality, you know the type. It's definitely a sickening movie, I feel like I don't wanna be there but I wanna be there because of the hot chicks, it's amateurish. Well we won't be seeing a typical family in there, it's a summer beach party of the college type crowd, and that's the setting of the movie, so don't expect a lovely kid being eaten by piranhas, we don't wanna see that. We wanna see careless people who only care about their pleasures, being slaughtered. This movie didn't went that far accepting the fact we did not see a nice happy family being digested, instead it became a joke as we saw a penis being puked by a piranha after fighting for it. It's almost funny to see a bunch of party animals screaming in terror after partying so loud. Yes, it scared the hell out of us to go in the water, obviously by using make-ups and special effects to make it realistic and gruesome. But unlike "Jaws" which made us think twice before swimming into the sea, using the crafty techniques by Spielberg inspired by Hitchcock, and the unforgettable score. The main characters aren't the hero types, but they are less annoying than Eli Roth. In terrifying us, it succeeded, but it doesn't have a good climax, it was not properly executed. Even the last heroic and dramatic scene wasn't believable, it's easy to say that they survived because they were the main characters. It lacks situations, difficult and inventive situations. It's a quick terrifying movie, it didn't hang around for a little bit more to give us a lasting scare. Although it's too much, it wasn't enough, you know what I mean? Am I excited for the sequel? I'm expecting it to be lousy, imagine a group of human size piranhas attacking us, isn't that ridiculous, it's like being attacked by all the sharks in the world. But I will be waiting for it, hoping to have laugh.
