What do these five famous actors have in common?
Dick Van Dyke
Peter Sellers
Sean Connery
David Niven and
Woody Allen.
The answer is not that they are all famous actors.
The title is relevant to the riddle.
All have appeared in movies based on Ian Fleming stories: Van Dyke in "Chitty Chitty Bang Bang," Connery in the James Bond series, and Niven, Sellers and Allen in "Casino Royale," based VERY loosely on one of the James Bond novels. It is accurate to say that four of the five have played James Bond. In "Casino Royale," Niven is the real Bond, Sellers is an expert gambler recruited to take on the identity of Bond, and Allen is Bond's nephew Jimmy Bond.
