Operation Amsterdam is a 1959 black and white British action film, directed by Michael McCarthy, and featuring Peter Finch, Eva Bartok and Tony Britton.

Needing a car, they commandeer one driven by Anna (Eva Bartok), who is trying to commit suicide because she blames herself for the death of her Jewish fiance's parents.

However, many of the stones are stored in a time-locked bank vault which won't open for 24 hours because of the Whit Monday holiday so they recruit Dillon's contacts, a Dutch resistance group, to break in.

Fifth columnist elements in the Dutch army launch an attack outside the bank but the group manage to break into the vault and recover the diamonds.

They commandeer a tugboat to take them back to the waiting destroyer, but Anna elects to remain in the Netherlands and work with the nascent resistance movement.

This was turned into a book Adventure in Diamonds by British journalist David Walker, which forms the basis of the film.

The others were Upstairs and Downstairs, Sink the Bismarck!, Northwest Frontier, Ferry to Hong Kong, The Wind Cannot Read and The Captain's Table.
