The Dollop podcast on George Lazenby is a hoot! The studio were absolutely terrible to the guy, they wanted him to emulate Connery but at a fraction of the cost, so made him do all his own stunts, then refused to give him any direction at all, despite him not actually being an actor. They only had him contracted for a single film, which became a smash hit but George had become a full on hippy and refused to go along with the aesthetic, so they wouldn't let him promote it, which became a big thing when they then tried to get him to sign on for a multi film deal, with loads of conditions he wasn't happy with.

In the end, it was a combination of poor management advice (on the longevity of Bond) and his not wanting to stop being a free full bearded hippy for x number of years, then we'd likely never have had Moore as a bond. George sounds like a good dude and the most unique Bond
