Haute Tension (French pronunciation: High Tension; released as Switchblade Romance in the United Kingdom and High Tension in North America) is a 2003 French horror film that was later released in 2004 in the United Kingdom and 2005 in the United States and Canada. The film, directed by Alexandre Aja, stars Cécile de France, Maïwenn Le Besco and Philippe Nahon. Haute Tension was picked up by independent distributor Lions Gate Entertainment following a successful screening at the Midnight Madness section of the 2003 Toronto International Film Festival. Originally rated NC-17 in the USA for Strong Graphic Violence, a few graphic shots were cut from the final version of the U.S. release to get it down to the R rating (the original NC-17 cut was released in some theaters). However, the original cut (referred to as an unrated version) is available on DVD. The film finally Rated R for Graphic Bloody Killings, Terror, Sexual Content, and Language.
