Though it isn't always the case, Bruce Lee's most famous movie is probably his best; Enter the Dragon is a martial arts extravaganza oozing in '70s culture, brilliant fight scenes, and a gripping plot that sees our hero - creatively named "Lee" - invited to take part in a competition on a private island, where upon he discovers an underground drug smuggling operation ruled by a mysterious character named "Mr. Han." Really, this set-up provides our protagonist with an excuse to take down a variety of unsavoury challengers in a badass ways. So although there's no hiding the fact that Enter the Dragon purely exists as a showcase for Lee's skills, there's also no denying that the movie - directed by the very underrated Robert Clouse with a brilliantly memorable score by the great Lalo Schifrin - also transcended its B-movie origins somewhat. Not only is the picture packed to the brim with an array of inventive, bone-breaking fight sequences, it also contains a fair degree of tragedy via a subplot regarding Lee's sister. And who could forget Lee's face-off against Jim Kelly, or the final battle in the hall of mirrors, where Lee goes up against Mr. Han and his deadly claws?
