It's not big and it's not a train. It's just funny. Big Train steams out of the comedy tunnel as realism meets utter stupidity in a cavalcade of daft sketches performed by high-quality actors in stunning costumes and vast sets reminiscent of the worst excesses of DW Griffith. There are also lots of sketches in offices. Along the way we meet shy policemen, pop stars chasing jockeys, a duck in danger, hens in armed combat, a confused Transport Minister, highly charged sexual politics and casual, though necessary, violence.
