Much imitated, but never bettered, Bruce Lee was the king of kung-fu movies.

This, his final film (he died three weeks before the premiere aged just 32), is one of the definitive fight films and, though no masterpiece as a movie, it turned Lee into an enduring international screen icon.

Stiff-backed, shirtless and, as ever, punctuating the athletic mayhem with his trademark yelping war cry, he’s on peak form as he smashes through an island fortress, a villain with a detachable hand and a splintering finale in a hall full of mirrors.

Many of Lee’s ferocious fight scenes were originally trimmed by the British censors ­- who surely missed the entire point of the movie ­- but have now thankfully been restored.
