Not enough David McCallum!
This movie (the first of eight 'Man From U.N.C.L.E.' movies made from TV show episodes) was made from the first two episodes of the first season. At this time Illya Kuryakin (David McCallum's character) was not considered a main character, only Napolean Solo was. It wasn't until later on in season 1 that the studio learned of the considerable popularity of McCallum's character with the show's younger fans. At the time the youth movement in the U.S. was causing "Hollywood" to give TV's younger viewers more and more credence. As a result, Illya Kuryakin's part was greatly expanded, making him Solo's "sidekick", so to speak. The same thing happened with 'Star Trek' a couple of years later. Mr. Spock wasn't originally meant to be a main character either. When Gene Roddenberry learned how popular Leonard Nimoy's character was getting he convinced Paramount Studios (or was it Desilu?) to do the same with his role.share
