Actresses seeking employment in films are wise to turn to the slasher genre. By their very nature, slasher flicks are always in need of women willing to be murdered in a scene of graphic violence and get naked, with emphasis on the latter. Busty babe Margaret Derbyshire is one such actress. In the direct-to-DVD frightfest Clay (2007), Margaret’s massive mams come out when she doffs her top for a shower scene. Those look more like boulders than clay.
