Tower of Death (1981) was the last official Bruce Lee release. The producers of The Game of Death were compelled to make another Bruce Lee movie after the success of the G.O.D. in Southeast Asia. So the director used what stock footage he had left plus doubling by Yuen Biao (stunt and acrobatic scenes) and Tang lung (a Korean actor who played in the Game of Death) not only doubling for Bruce but also playing his brother. It was very inventive how the director managed to put in the Bruce Lee scenes. You get to see a lot of Yuen Woo Ping's action directing in this movie.
