• Introduction by Linda Lee Cadwell (2:11) - This DVD-era video introduction, playable either on its own or optionally before the Special Edition, features Bruce Lee's widow who goes into light detail about the reinstated "philosophical" footage and why it was important to her late husband's vision for the film.
  
• Audio Commentary - Another DVD-era supplement also included on both WB Blu-rays, this feature-length track pairs up the film's producer Paul Heller and writer Michael Allin. It's dryly technical-minded rather than warm and retrospective, with portions of the conversation feeling more than a little disjointed since Allin is participating via phone instead of in-person (a criticism any post-2020 person understands all too well). Certainly not the finest audio commentary in existence, but decent enough and at least peppered with first-hand info.
