Made by Bond-producer Harry Saltzman as the antithesis to the Bond franchise,this clever little spy yarn gives Michael Caine one of his iconic roles as "Harry Palmer".He would do the part in two subsequent films in the sixties which helped him cement his fame.This movie is not for those who want action packed spy-adventures because it's pace is rather slow,focusing more on character than action. The movie's plot isn't very realistic,but quite entertaining. The script takes some witty pot shots at the spy-genre and at the British society. The depiction of sixties London as a dark and gritty place where danger lurks around every corner is very good. I must say I enjoyed "The Ipcress File" a lot.
