I don't know when this guy originally posted those remarks, but he's wrong about there being no DVD. A very nice one was released in R1 by Olive Films last March. Glen Erickson gave it a review: http://www.dvdtalk.com/dvdsavant/s3833man.htmlIt was due to that review that I bought a copy (not remembering at the time that I'd already seen the film on TCM).
No Man of Her Own (1950) 10/10. Not really a noir--call it a woman's picture with noir trimmings. Barbara Stanwyck is in NY, broke, pregnant, and jilted by Lyle Bettger. Lyle's all heart: he buys her a rail ticket back to San Francisco. Turns out to be the best thing he could have done, though. On the train she meets a kind couple her own age who are also expecting, and when the train crashes and the couple are killed, Barbara is mistakenly identified as the dead man's wife. Turns out the guy was from money, and since the family hadn't yet met the wife, it's easy for Barbara to go on pretending she's the mother of the family's heir. She's no grifter, though; Barbara is doing it for da chile. Her new brother-in-law (John Lund in Handsome-Block-of-Wood mode) has his suspicions, but he soon succumbs to Barbara's charms. Things are going swimmingly--and then Bad Penny Lyle turns up. It's not long before several people have a motive for murder. Referring to Lyle at the end, a police detective remarks, "He must have been quite a guy. Everyone who knew him wanted him dead." The rock-solid plot is derived from a novel by William Irish (Cornell Woolrich).
