Angels Warehouse has always been a cool place to find quirky gifts. Basically they are the main costumiers for movies filmed in the UK, and they've now put their catalogue online.
Note: Servers seem a bit thin, so expect some time-outs.
So far I've found:
Kirk Douglas's suit from the TV series "Queenie"
Prince Humperdink's tunic from The Princess Bride
Sean Connery's Tail-coat from The First Great Train Robbery
Benny Hill's Judo Top
There's Star Wars, Monty Python and James Bond stuff too, and some of the prices are far less than I'd expect.
