Which rock star had a role in the 2000 film 'U-571'?

Player Elf Counsel, Good thing world peace is not based upon your hatred towards the Americans!

I thought the Poles played a major role in either acquiring an Enigma machine or cracking the cypher - or maybe both.

GameShowHost, It was certainly a Brit that learned how to understand it. Having it wasn't worth nothing.

The British actually captured the Enigma machine, not the Americans as portrayed in the movie.
