The "endless game" is espionage, which goes on and on despite government upheavals and changing international attitudes. Albert Finney plays a retired secret agent called back to active duty. Finney is entrusted with the task of finding out why his fellow retirees are being killed off. One of the victims is a woman who'd once been Finney's lover. Anthony Quayle makes his final screen appearance in this made-for-cable suspenser. Endless Game was written and directed by Bryan Forbes--surprisingly, his first foray into the spy-film genre.
