MichaelCaine played British secret agent Harry Palmer in five films, based on a series of novels by LenDeighton.

The first three -- ''The Ipcress File'', ''Funeral in Berlin'', and ''Billion Dollar Brain'' -- were released in the 1960s, during the height of the Sean Connery Film/JamesBond films, and offer a grimmer alternative to the flashy espionage of Bond. (In this wiki's SpyFiction rating scale, the Bond films are Martini Flavored and Palmer films are very definitely Stale Beer.)

Caine returned to the role thirty years later for two more films, ''Bullet to Beijing'' and ''Midnight in Saint Petersburg''.
!!Films in this series with their own trope pages include:

* ''Film/TheIpcressFile''
* ''Film/FuneralInBerlin''

!!The other films in this series provide examples of:

* GeneralRipper: General Midwinter (Ed Begley Sr.) in Ken ''Billion Dollar Brain''.
* NamedByTheAdaptation: Harry Palmer. The narrator-protagonist of the novels never gave his name.
* SpecsOfAwesome: Heavy-framed National Health Service spectacles form part of Harry Palmer's deceptively insignificant-seeming appearance.
