Aside from some bad acting from Evalyn Knapp at the beginning of the picture, "The Fire-Trap" is an otherwise decent little B-movie. Like most Bs, it does have a cast of lesser-known actors, lower production values and a running time of about an hour. It's not at all a distinguished film or one you should rush out to see but it is an amiable time-passer.
The film begins with Betty (Knapp) behaving like an obnoxious, spoiled rich girl--which is pretty much her character. However, after she falls for Bill (Norman Foster) she becomes a softer and more believable character. Bill is a fire investigator and neither he nor Betty realize that her father is planning on deliberately burning down his own business and claiming the insurance. Can this be stopped in time? Yeah,...whatever.
The best scenes are near the end with the fire--the worst, clearly, at the beginning. The bottom line is that if you do choose to see this film, it is only fair and the DVD copy from Alpha Video is awfully bad. So, overall, I really cannot see a lot of compelling reasons to see this film.
