Hopscotch, 1980 directed by Ronald Neame and staring Walter Matthau as Miles Kendig.

Kendig's boss at CIA tries to force him to retire. He balks at retirement and writes a tell-all book. CIA and KGB try to stop him. He leads them on a wild goose chase and finally fakes his own death by flying and destroying a biplane via remote control.

I like this movie because it is unusual for the spy movie genre. It doesn't revolve around gadgets or violence or sex as it does around duplicity and wit.
