The world’s most famous secret agent is turning 50 – the James Bond film franchise is marking five decades since the October 5, 1962 release of Dr. No, the first movie of the series produced by London’s Eon studio.

Twenty-two movies and countless shaken-not-stirred martinis later, moviegoers are trying to sum up -- and rank -- the exploits of those who have portrayed Her Majesty’s best spy over the years.

Worldcrunch avoided the temptation to rank the best sex scenes, car chases or quotes  - and chose instead to crunch each of the six actors down to a single adjective.

And James, don't ever forget, the English teachers love you too...

SEAN CONNERY – unforgettable

GEORGE LAZENBY – forgettable

Roger Moore - indefatigable

TIMOTHY DALTON - inscrutable

PIERCE BROSNAN -  unmussable

DANIEL CRAIG – unbelievable (for his believability!)
