If people watch that last scene, in which Lazenby performs so great (don't think anybody could have done it better and it's possibly one of the most crucial scenes in the series), how can they say he can't act. I just cannot understand the criticism. Thankfully most fans and even critics admit he did a great job.
You took the words right out of my mouth. I don't understand why Lazenby gets so much criticism for what was, in my mind, a bang-up job. I suppose it stems from the over-used phrease of "his only previous acting work was in a chocolate commercial". Hell, all actors have to start somewhere! There'll be some poor sod out there doing extra work and Starbucks adverts who can act like Laurence Olivier. He just hasn't come to public attention yet. This is what I think occurred with Lazenby - someone who could act perfectly adequately but was bashed for his lack of experience. However I will agree that his attitude off screen was less than professional.
