Bruce Lee Unleashes the One-Inch Punch in 'Birth of the Dragon' Trailer A Bruce Lee biopic sounds like a dicey proposition. How could watching someone pretend to be the greatest fighter of all time (by all means, @ me) accomplish anything other than making the audience wish for the genuine article? But judging from the newly released trailer, Birth of the Dragon has a fair amount going for it. For one, it has the good sense to focus on a single period of Lee’s life, narrowing the film to his early years in San Francisco, when he was building his legendary reputation.
