Five of Deighton's novels have been adapted to film: The Ipcress File (1965), Funeral in Berlin (1966), The Billion Dollar Brain (1967), Only When I Larf(l969), and Spy Story (1976). In addition, the film rights to An Expensive Place to Die have been sold. The anonymous hero of Deighton's novels is given the name Harry Palmer. In the film version of The Ipcress File, Michael Caine plays the protagonist as a slightly seedy Cockney, a not entirely authentic but satisfactory interpretation of the character.
