9 Movies With Way Too Much Gratuitous Nudity

5. Piranha 3D

In 2010, director Alexandre Aja decided to cash in on the 3D boom that followed in the wake of Avatar with his revamping of the Joe Dante-directed 1978 cult classic Piranha. Aja utilized 3D to deliver horror fans the pulpy thrills they expect from the genre, including excessive nudity and sex scenes rendered in all 3 dimensions. One particularly memorable scene occurs when two of the female characters engage in an extended underwater lovemaking session that lasts for minutes onscreen; this scene has no bearing on the plot, or, the development of the characters as individuals and is therefore completely gratuitous.

Despite Piranha 3D's stomach-churning gore and superfluous nudity, critics took the film's excesses as a tongue-in-cheek homage to the horror genre and gave the feature a favourable 73% rating on the review aggregator website Rottentomatoes.com. Audiences also responded kindly to Piranha 3D's over the top spectacle, making it a hit to the tune of $83 million dollars at the world-wide box office.

A sequel, Piranha 3DD followed in 2012, retaining the excessive nudity but none of the wit or winking homage. Even though critics decided to look the other way, there's no denying that Piranha 3D takes its homage to pornographic extremes and loses sight of the satire in many instances.
