I agree with the others who posted about this movie. It is very enjoyable. The DVD I have was made from a pretty bad print but I still made it through and appreciated the film very much. Onslow Stevens was quite a leading man back then. I agree that he could be just as effective today with his laid back acting style. The actress who played Sylvia was very, very beautiful. She and Stevens had great chemistry. I also liked the older actors, especially Howard Lang. There is a very funny bit where he and the older female character are swapping barbs about the old man's fondness for the eye candy at the pool. The entire pool scene was a blast, especially since we get to see Sylvia in a rather revealing swimsuit (along with some other vintage beauties)
There really isn't a lot of mystery here as we know who the bad guys are right away. However, the best and most effective plot device is the love at first sight between the two leads, one of whom is simply pretending to be the girl's long lost love. This really works great and leads me to believe that this film might work very well as a remake (This has Hallmark channel written all over it) I really liked it, a fine old film with a great cast that was fun to watch. According to this website, the actor who played Martin has no other film credits. He was pretty darn good in this, his only role!
