Watched on youtube today, and I found this a revelation. Jerry Verno is incredibly likeable as a young plumber who just happens by chance to also be a Lord (not something he is keen on). For the first two thirds of the movie Verno is almost ever present as a calm at the centre of a whirl of comedic intrigue. His performance is very natural and not over-played like many contemporaries.
Indeed Michael Powell pulls very good performances from much of the cast, most notably Muriel George and Ben Welden as a vigorous publicity agent. The music is enjoyable, the choreography on a shoestring eyecatching and the pace of the movie exhilirating.
Even an autogyro to look out for at the climax. But Jerry steals it for me...wish movies had made better use of him.
