It has never been released in the UK, either in the cinema or on VHS/DVD format. The film critic
Barry Norman campaigned for a cinema release, but it never happened. BBC 2 have screened the film late night (well early morning really) a couple of times. A friend gave me a DVD of the work print which has an alternate ending to the North American release, which I have not watched. If you have not seen this film and ever get the chance to do so, please make the effort :)
