Okay, I'll admit that this movie is a bit heavy-handed at times. Lionel Barrymore's performance as Mary's father is not a subtle performance and the movie is a tad predictable at times. However, despite these minor shortcomings, this is a marvelous romantic flick from Hollywood's heyday and is a great early Gregory Peck vehicle.
Mary (Greer Garson) is a lovely poor lass who goes to work as a housekeeper in the home of the wealthy family (the Scotts) who own the local steel mill. This is problematic, as Mary's father was seriously injured in the mill and bears an intense hatred of the Scotts. It becomes even more problematic as, over time, handsome Paul Scott (Peck) falls for her and asks for her hand in marriage! Yikes! However, this is only about half-way through the movie--what happens next you'll need to find out yourself.
Great performances (not just from the two leads but from capable supporting actors such as Donald Crisp and Dan Duryea), direction, sets and writing make this one of my personal favorites. Watch it!
