Roadhouse Girl on AllMovie

The British Roadhouse Girl was released in the US as Marilyn, but don't go looking for Ms. Monroe around these parts. Sandra Dorne plays Marilyn, the sexy young wife of ill-tempered garage owner Leslie Dwyer. Assuming that his wife is fooling around with mechanic Maxwell Reid, Dwyer begins punching Reid out. Defending himself, Reid accidentally kills his boss. Marilyn helps Reid cover up the crime, and together the two strike out to find a new life. Several months later, the couple is running a just-getting-by roadhouse. Wealthy Ferdy Mayne agrees to lend the couple some money, figuring the Marilyn will offer her affections as repayment. But things take a sorry turn when Mayne begins to suspect that Reid has committed a murder. Though based on a play by Peter Jones, Roadhouse Girl seems heavily indebted to James M. Cain's The Postman Always Rings Twice.
