OK, it was made by the CFF, but even so, it was dire, with silly slapstick that I doubt most kids wouldn't find funny - L&H or Chaplin it certainly isn't!! Which is a shame as I like Peter Butterworth (again), who is the only person credited with appearing in this, despite other actors and actresses.
1/10 for curiosity value
