The Iron Maiden

This largely misfiring British comedy from Carry On director Gerald Thomas attempts to marry The Maggie and The Titfield Thunderbolt, but ultimately fails to match either. Yet again we have grown men going weak at the knees over a piece of clapped-out machinery, but here it's a traction engine instead of a boat or a train and, frankly, it strains for the same level of romance. Off to a slow start, the picture falls away towards the middle and finishes with a traction race that's hard not to like, even if it does steal every "aren't enthusiasts funny" joke that escaped being nailed down in Genevieve.
