On Her Majesty's Secret Service(1969)

Ok, Before you say this is the worst of the Bond Films, just remember, The Aussie James Bond, "George Lazenby" was slated to do 7 Films, So we would have had alot more George except for the fact that the Producers of the 007 Films basically wanted him to live entirely their way for the next 10 or so years. You must do this, you musn't do that, always clean shaven in public, you will eat where we tell you, drive what we tell you, wear what we tell you. Addmitedly this came with a 25 Million price tag. However, when he asked for 35 Million, the studio went back to Connery.
Also, I think, and this is just my own opinion, but the Subject matter and story line of this Bond film made it one of the hardest Bond Roles to play.
