The Vector Prime television commercial was released in late 1999 to promote the release of the novel The New Jedi Order: Vector Prime, the first entry in The New Jedi Order series. It featured a narration by Mark Hamill as Jedi Master Luke Skywalker, speaking over a montage of scenes from the Original trilogy as The Emperor's Theme played.
The commercial aired on the Sci-Fi Channel and FX beginning on Monday, October 18th, 1999, and it ran several dozens of times over the ensuing weeks to promote the novel, include several spots during prime-time television hours. On FX, the commercial played during syndicated runs of The X-Files and Millennium. An online copy of the commercial was eventually added to the StarWars.com page for viewing and download.
In 2022, Mark Hamill was asked if he remembered doing the voice-over for the commercial on Twitter, along with a link to a remastered version of the commercial. Hamill liked the tweet with the video, responding, "Wow. I have no memory of doing this at all. It's like seeing it for the first time. Thanks for posting, Ackbarfan."
