A different kind of spy movie that I adore is Hopscotch.
Made in 1980/1ish. A well seasoned CIA feild agent with 30 years experience is given a desk assignment as punishment for letting a KGB spy go. Literally. (You will understand his motives.)
Instead of being benched, the spy destroys his paper files(this is before computer stuff.) and decides to go walk about trying to figure out what to do with his life.
He decides to write his tell all memoirs of the dirty secrets of the CIA. And he sends off one chapter at a time to the KGB, CIA, Interpol and Scotland Yard…leading a merry chase hopscotching about the globe one step ahead of the CIA.
In the end, you are happy for him and how he takes care of his wonderfully egotistical boss.
Walter Matthau plays the Agent. Sam Waterstone , a very young San Waterstone ( or whatever his name is from Law & Order) has a lovely little part. The Boss Who Gets His Comeuppence is the ever evil Ned Beatty.
More fun than cloak and dagger.
