'The Rapists'), is a 1981 Swiss–Spanish vigilante action film directed and co-written by Paul Grau, starring José Gras, Laura Premica and Eulalia "Laly" Espinet.

Mad Foxes is regarded as a quintessential example of European exploitation cinema, and has been noted for its lurid violence and disjointed plot, which initially caused producer Erwin C. Dietrich to disown it.

[6][8] The director convened with a friend who worked for Swiss tabloid Blick, and they hastily cobbled together eight pages worth of sensational crimes that would form the synopsis of the new project.

[6][9] Some of the men hired to play the bikers were actual Hells Angels, with whom actor Eric Falk had had a heated encounter during his day job as a bodyguard.

[11] Zurich, Switzerland, hosted interior scenes while the rest of filming took place in Barcelona, Spain, in partnership with local company Balcázar Producciones.

[3][7] Mad Foxes opened in Germany on 14 August 1981 through Dietrich's company Ascot Film, drawing an estimated 225,000 admissions over its national run.

Every single element screams outrageousness — from its tasteless acts of violence and gore to its non-stop slate of sexual shenanigans and nudity (including some startlingly casual male full-frontal shots).

[31] American publication Shock Cinema deemed that Mad Foxes "takes you on a truly rancid joyride" which "flows along with its own unfathomable logic" and "combines the brutality of Last House on the Left with the rampant stupidity of Eric Von Zipper.

[6] Towards the end of his life, Dietrich had come to grips with the film's dubious legacy and looked at it more amusingly, even though its censorship issues prevented him from recouping all of his investment.

The song and accompanying footage, which was taken from a TV spot made by Grau for the band's 20 Rock'n'Roll and Boogie-Hits album, were spliced in to pad out the running time after it came up short.
