"The Assassination Bureau" (1968) An unappreciated treasure

Paramount Pictures did not give this stylish (and quite expensive) adventure/comedy much love in 1968. The US release added "Limited" to the title to make the title less dark.
Michael Relph's art direction is especially noteworthy. Diana Rigg and Telly Savalas would star together a few months later in the Bond flick "On Her Majesty's Secret Service".
