As James Bond celebrates the 50th anniversary of his big screen debut on October 5, MSN attempts to definitively answer the question of who the best Bond actor is

Six men have officially had the honour of portraying Ian Fleming's sophisticated spy on the big screen, and every fan has an opinion on who their favourite is.

Using our huge pool of movie-loving users around the world, MSN has decided to launch a multi-national poll to determine once and for all which actor's portrayal is head and shoulders above their contemporaries.
