Mrs. Winterbourne (1996)

A young girl (Ricki Lake) finds herself unmarried and pregnant by a sleazy petty thief (Loren Dean), who wants nothing to do with her or their child. She is on a train when she meets a newly married couple (Brendan Fraser, Susan Haskell) and she is also pregnant. When the train crashes, the couple are killed and through a misunderstanding, authorities believe she is the wife and the man's family take her in as the daughter in law. Based on the novel I MARRIED A DEAD MAN by Cornell Woolrich and directed by Richard Benjamin (MY FAVORITE YEAR). I don't know who thought it was a good idea to take Woolrich's dark novel and turn it to a romantic comedy but it's an uncomfortable fit. The novel had been made into a decent film in 1950 (NO MAN OF HER OWN) with Barbara Stanwyck which played it straight. Here, the romcom elements clash with darker elements like Loren Dean's blackmailing sleazebag and his eventual murder. In addition to playing the deceased husband, Fraser also plays his twin brother. With Shirley MacLaine, Miguel Sandoval, Paula Prentiss, Jane Krakowski, Debra Monk and Peter Gerety.
