Vulcan - //I admit I enjoy the acting of Caine & Connery but they are not totally convincing and I think the problem is with their voice. Connery for example sounds exactly the same whether he is James Bond, Robin Hood or a Russian submarine officer. //
I can't agree.
All actors have the voice they are born with - they learn to adapt it, along with changing their posture, and entire persona.
Look at Paul Whitehouse as a shining example - Unlucky Alf, Rowley Birkin, Ted, Suit You Tailor, Self-Righteous Brother, Mike Smash - the list goes on and on and he is utterly different as all of them.
