Brand new factory sealed dvd is Out Of Print and only available as a blu-ray.

This quaintly Agatha Christie-type plot and characters are set in an ever-so-English locale: Gothic atmosphere in an old theatre by the seaside. A company of actors arrive to rehearse a Grand Guiginol play for an employer none of them has met. The unseen employer turns out to be a maniac, an ex-leading actor whose hatred for the profession has festered ever since he murdered his wife and her lover by entombing them following a performance of 'Othello'.

The film then chronicles the maniac's decimation of the troup. Although the film has a window dressing of sexploitation and some misjudged humour, it retains a degree of charm. An early prototype for body count slasher films that would soon permeate the market.
