lamentropy’s review published on Letterboxd:
This is the only 'normie' movie Ken Russell made in order to gain money to make Women in Love - very much valid reason, no any other questions are needed. And though it's a spy movie - third in a row of Harry Palmer's adventures - Russell made the most out of it, adding his unique style and atmosphere on the verge of surreal.
It's the closest to campiness it can get, and I had much fun with watching our secret agent travelling from London to Helsinki to somewhere in Latvia to Texas and back again the same route. Michael Caine is brilliant handsome devil who gets the girl first moment they see each other, but actually, all he truly wants is a piece of quiet and to eat some cereal.
