"The Ghost and Mrs. Muir" (1947) - 6/8 Starring Rex Harrison, Gene Tierney, George Sanders, and a very young Natalie Wood.
Finally sat down to watch this on TCM the other night. Have always been reluctant to because I still remember watching the 1968 TV show with Edward Mulhare and Hope Lange in the starring roles, and it was just a cheesy sitcom. I couldn't have appreciated the movie back then, but it is a treasure for the time it was made in. Similar in feel to "The Uninvited" (1944) with Ray Milland, although that one is more of a horror story then a romance.
