This was the final film in the Matt Helm series. Although plans were afoot for a fifth film ("The Ravagers"), as well as a proposed teaming with Frank Sinatra for "Matt Helm Meets Tony Rome," the poor box-office showing of both "The Wrecking Crew" and Sinatra's second go 'round as Rome in "Lady In Cement" brought the Matt Helm series to an end.
The film was shot during late 1968 and released in 1969. The American president appearing here is still suggested to be Lyndon Johnson (back of head, ears, voice, accent) although Richard Nixon had succeeded him.
Count Massimo Contini: Actually, I would have preferred to live in a different century, Florence in the 13th or Germany in the 18th. Wouldn't you, Mr. Helm?
