That clip looks like the Mark Hamill doc that aired on the Biography Channels 'Star Wars Knight' lineup, around the time of Episode 3. That clip is identical to the start of that doc, only for some reason the Biography one doesn't have the 'Force to be Reckoned With' title appear after Hamill's signature draws on screen.

This and other 'Star Wars Knight' biographies on Lucas, Ford, Fisher and Samuel L Jackson were at the time preserved and released by Segaflip.

Coincidentally, it looks like the Hamill one may be in for another showing in September.
