Piranha (film series)

Piranha is a horror film series that consists of five films. The original film is a parody of the 1975 film Jaws.

Piranha (1978)
Piranha is a 1978 American horror B movie about a swarm of killer piranhas. It was directed and co-edited by Joe Dante and starred Bradford Dillman, Heather Menzies, Kevin McCarthy, Keenan Wynn, Barbara Steele, and Dick Miller. Produced by Roger Corman, Piranha was inspired by the 1975 film Jaws, which had been a major success for distributor Universal Studios and director Steven Spielberg. It has since inspired a series of similarly themed B movies such as Grizzly.

The film involves a private investigator Maggie McNamara from Lyon Investigation. She was hired by the wealthy J.R. Randolph to find his niece, who disappeared with her boyfriend. Maggie seeks out the lonely environmentalist Paul Grogan to help her to look for the teenager. They head to an abandoned army facility and Maggie decides to drain the pools to see if the body of the girl is one of them. They are assaulted by a man with a crowbar, but they subdue him. However, he escapes, and soon they learn that the man is Dr. Robert Hoak, who, for military purposes, is researching a hybrid species of piranha that is capable of surviving in fresh and sea waters. Furthermore, Maggie has released the piranhas in the river, and they are heading to the Lost River Lake Resort.

Piranha II: The Spawning (1982)
Piranha II: The Spawning, also known as Piranha II: Flying Killers, is a 1982 horror film and the sequel to the 1978 low-budget cult film Piranha.  The film is the feature film directorial debut of James Cameron.

Piranha 3
Piranha 3 was announced in October 1991 as part of a slate of films to be produced by Ovidio G. Assonits' International Movie Service in Variety for sale at the American Film Market. The plot concerned a scientist releasing flesh-eating fish into the pool system of a ski resort. The film was never made.

In April 1994, rights holder Chako van Leeuwen announced the revival of her film company, Chako Film International, to produce Spirit (later released as Raging Angels with Sean Patrick Flanery and Diane Ladd) and Piranha III to be backed by United Artists. Again, no film was produced.

Piranha (1995)
Piranha, also known as Piranhas, is a 1995 American horror film directed by Scott P. Levy about a school of killer piranhas descending upon the bustling Lost River Lake Resort.

Piranha 3-D: The Invisible Menace

Piranha IIID
During production and post-production of Piranha 3DD, Dimension Films began developing a follow-up, entitled Piranha IIID but due to the commercial failure of 3DD no film was made.
