This film is actually mainly interesting as a record in its own right of the local (?Brighton?) variety acts who were featured to fill out the running time; they are notable in two respects, in that by modern standards none of them are particularly glamorous-looking, and in that they are actually all pretty talented -- these are run of the mill and nowadays apparently forgotten pier-end performers of the day, as it were, and they're still entertaining to listen to. (The only act I really didn't take to was that of Freddie Mirfield and his Garbage Men, with their knockabout orchestral gags.)
The Goon Show contribution consists of various improvised comedy dialogues chiefly featuring Peter Sellers in a selection of different characters: his Groucho Marx impersonation is rather good, others vary. Considering that the whole thing was made up and then shot by Sellers and Spike Milligan in the course of a left-over week of studio time (remaining after shooting on "Penny Points to Paradise" had been completed), it's quite tolerable, but of course by no means a classic.
