The release of "Millennium" on DVD prompted Lance Henriksen to propose a continuation of the series. Henriksen speculated that the numbers behind the box set sales might be the key to reviving Frank Black. "I wonder if the sales of these will tell us how many people loved the show and whether or not the movie ought to be made," Henriksen told the Sci-Fi Wire. "I mean, Black still is alive. Maybe it's a good thing there was no closure for "Millennium" because now, if we did a movie, it would be good closure for me." Henriksen has gone on to support the Back to Frank Black campaign, a movement dedicated to the return of the character, explaining, "I really think it is a possibility."
