I'm sure I must've seen this when I was younger but all the detail had passed me by so I came to it fresh. Russ Tamblyn is phenomenal, both in acrobatic ability and charm. He's so perfect for the role that I honestly can't imagine anyone else playing it with such energy. The rest of the cast is equally as enjoyable, Terry-Thomas and Peter Sellers in fairly typical roles for them and hamming it up something rotten. I enjoyed the interplay between June Thorburn and Alan Young and, really, every minor role was brilliantly cast.
This is a very flamboyant, colourful film and it has two centrepiece musical numbers - 'Tom Thumb's Tune' and 'Talented Shoes', both of which are extremely catchy and likely to torment you for days. The first is Tom's greeting by the toys in his room which showcases Tamblyn's athletic ability wonderfully and the second is a number in the town square with - you've guessed it - talented dancing shoes. If I have one niggle with this film it's that the scene in the villains' lair went on a little too long but it was funny enough and gave a little tension to the finale. The special effects are not at all shabby for 1958, not spectacular by any means but in keeping with the story as a whole and thoroughly enjoyable.
Definitely one I'd rewatch - and perhaps with my father too since he came in the room for two minutes and stayed for half the film!
