Killer Bitch is a 2010 (2010 in film) British action/gangster movie, written and directed by Liam Galvin.

The film became notorious in the UK in August 2009, shortly after shooting started, when tabloid newspapers the News of the World and The People carried stories implying that the movies star, Katie Prices then-boyfriend Alex Reid (Alex Reid (MMA)) had been involved in a "vile" rape scene and that Killer Bitch was a porno film (Pornographic film). This was denied by Price who claimed that neither she nor Reid would in any way be involved in a film glorifying rape as she herself had been raped. This further stoked controversy.

Reid was subsequently reported to have walked off the movie leaving several of his scenes un-shot. The producers shut production down for six weeks and re-wrote the script retaining Reids completed scenes but filling-in the gaps with eighteen new scenes featuring former football hooligan Jason Marriner and former world champion boxer Robin Reid (Robin Reid (boxer)) (no relation).

The film featured several alleged career criminals, Page Three models and boxers, cage fighters and martial arts competitors. The publicity storm surrounding the movie in the UK was stoked around the world including Australia, the Middle East, India and the US. and when, during post-production, Alex Reid won the British TV series Celebrity Big Brother (Celebrity Big Brother 2010 (UK)).

Further controversy surrounded the movie in March 2010 when the British Board of Film Classification, after four screenings, was said to be unhappy about the movies sexual content and would demand cuts to Alex Reids sex scene. In fact, they passed the while movie un-cut with an 18 certificate.

The original publicity for the film had said it involved real fights, real criminals, real sex; after release, the films executive producer claimed "the movie features real violence, real gangsters and real hardcore sex scenes".
