I saw this film at a matinée in 1962 when I was seven. I remembered it over the years as 70 minutes of pure excitement. I watched it again on DVD with my kids. Yes, it is low budget. Yes, it has cheesy special effects by today's standards. Yes, it has a corny plot and weak acting from some of the characters. Yet, I found it to have charm and my kids were just as enthralled as I was 43 years ago when I suspended my disbelief in the dark of the Saturday matinée. This film is, in its genre, a minor classic. Further, Basil Rathbone as the heavy is very good in the waning years of his life and career--much better than Torin Thatcher who played similar "heavy" roles in similar adventure movies.
