I've just watched a film which features:-
James Bond, The Prisoner, Inspector Dreyfus, Dr Who, a "Carry On" movie stalwart, Cowley from TV's "The Professionals" and, much to my surprise, one of The Men from Uncle. It also starred a man who "fired at will" (Poor old "Will" - five times as I recall!)
The film features an ending which will put you in mind of "The Italian Job" - Michael Caine's version that is.
And it features a line which could have come straight out of "The Prisoner".
Any guesses? It's not that difficult. And it was one more step, for more than one, on the road to 1960s stardom.
