This is the kind of movie made with care and respect for the audience:lavish sets,dazzling costumes,and a very attractive cast including Diana Rigg,Telly Savalas -both teamed for "on her majesty's secret service" the same year-,Philippe Noiret,Curd Jurgens and the sadly missed Oliver Reed.
The screenplay is often full of wit and humor,with such lines as "if there's a war,people will kill each others for a penny,and we will have to shut up shop (our "assassination bureau").Actually the whole movie is a long chase through a chocolate-box Europa with a lot of traps,bombs and disguises.Diana Rigg's appearances run the whole gamut from a Victorian prude resembling Mary Poppins to a femme fatale,from a widow in deep mourning to a nun,she's astonishing.So does (and is )Oliver Reed,who plays some British Arsène Lupin.History is given a rough ride when Francis-Ferdinand is murdered in Vienna (instead of Sarajevo) but who cares?
Best scene:Diana Rigg is alone in her hotel bedroom in Venice,Italy:she can hear a ticking.No,it's not the clock.So she rushes into her bathroom where a tap(faucet) is dripping.But when it's closed,the noise still remains.Is-it a bomb? .The brothel scene where Rigg is mistaken for a hooker is also great fun!
Two movies made in the seventies might have been influenced by Basil Dearden's amusing comedy:Douglas's Hickox's "theater of blood" (1973) also starring Rigg- a treat that should not be missed-and Ted Kotcheff's "who's killing the great chefs of Europe?" (1978)-Jacqueline Bisset cooks a bombe glacée here-.The people who liked this movie could do worse than picking those delightful black comedies.
