In this messy, hammy delivery room, Bruce Lee gives birth to the modern action picture. Extras include crisp versions of movies the star didn't get to make and Lee kick-fighting against a judo-mad Kareem Abdul-Jabbar (and you just might recognize that bright-yellow tracksuit he's wearing). If kung fu is now the standard badass language, Enter the Dragon -- featuring Lee's great slow-burn stare -- is the first grammar lesson.
