The film has suspense , tension , emotion , mystery and specially in its final a little bit of violence . Although the picture has various ingredients for entertainment , the screenplay is confused and complex , the plot has gaps and results to be sometimes embarrassing and absurd . This movie was made and released about four years after its source novel of the same name by Noel Behn was first published in 1966 and this was the first ever adaptation for cinema of a work by Behn . This exciting picture was filmed in four countries: Finland, Italy, Mexico, and the USA ; the scenes set in Moscow were shot in Helsinki, Finland . A number of characters in this movie are known by code-names , these include "The Highwayman" (Dean Jagger); "The Whore" (Nigel Green); "The Warlock" (George Sanders); "Erector Set" (Niall MacGinnis) ; "The Negress" (Vonetta McGee); "The Priest" (Marc Lawrence); "The Dentist" (Victor Beaumont) and "The Puppet Maker" (Raf Vallone) . The film belongs to spy sub-genre developed during the cold war and its maxim representation are John LeCarre's novels adapted to cinema in various films such as: ¨The spy who came in from the cold¨ (by Martin Ritt with Richard Burton), ¨Deadly Affair¨(Sidney Lumet with Maximilian Schell) and Russia House (Fred Schepisi with Sean Connery) . The star studded casting is important with known international actors but with a blurred writing they appear acting with no sense . The film was regularly directed by John Huston (who acts in a very secondary role) . Rating : Mediocre , though entertaining .
