Star Wars: The Force Unleashed (project)
After the "Unleashed" franchise was discontinued following Disney's decision to refresh the "Star Wars" canon in favor of producing a sequel trilogy, Sam Witwer, Marek's voice actor, revealed that Dave Filoni, the creator of the "Star Wars Rebels" animated series, considered bringing Marek back into the new canon and having him appear in that series, but ultimately decided against it because he could not find a way to do so without compromising either the new canon's quality or the character's unique distinctions.
Darth Vader
In the "Star Wars Holiday Special", a television special broadcast by CBS in 1978, features a brief appearance by Darth Vader, who appears on-screen speaking with Imperial officer "Chief Bast" in footage cut from the original 1977 film. The sequence is dubbed with new dialogue, performed by James Earl Jones. In the story, Vader colludes with Boba Fett to entrap the Rebels.
