The answer is simple - the one you liked best. I find it hard to believe that no-one has ever commented on this particular Bond doco.. has no one seen it?
Hosted by who was originally Ian Fleming's personal choice as Bond - Roger "The Saint" Moore, this is fun stuff from beginning to end. All the gang's here - a generation of Bond people all espousing their own theories. The entertainment comes from seeing them all together in the one show...albeit twenty to thirty years later in some cases.
If you call yourself a Bond connoisseur - you have to see this film!
