First sequel to The Ipcress File, with Michael Caine as blockbuster spy author Len Deighton’s bespectacled kitchen-sink Bond, Harry Palmer. Made in 1966, it doesn’t have that first film’s grubby chic, and the convoluted double-crossing gets almost impossible to follow, but there’s much to enjoy, not least Berlin in all its drab Cold War glory, and Caine’s sullen, funny, unblinking cool as he travels there to unravel the story surrounding a Soviet officer wishing to defect.
