Saturday Film Club: Behind the scenes at the Thrill-O-Matic

I don't like funfair rides. Yes, this makes me a bit of a wuss, but I don't care. 

However, if I visited Blackpool Pleasure Beach, I'd be tempted by the gentle charms of the Wallace & Gromitt "Thrill-O-Matic". I'd be even more tempted by the chance to tour the inner workings, but we can at least do this via YouTube.
