The Ipcress File was reasonably entertaining while I was watching it, but after it was over I felt I'd been had.

[Sidney] Furie is a sensitive director and the film is not a total sell-out.

Michael Caine is the epitome of Sixties cool in his first outing as the secret agent Harry Palmer.

It's cunning, calculated and still works, thanks to some droll humour, John Barry's marvellously twangy score, Sidney J Furie's energetic direction and spot-on performances by Guy Doleman and Nigel Green as bowler-hatted spooks.
