William Shatner knows how hard it is to become a bona-fide science fiction star. That’s why he’s making it a little bit easier for the next generation of would-be Captain Kirks. William Shatner announced today that he is holding an on-line contest to find the most talented sci-fi personality in the United States. To enter, contestants just have to create a short video clip that shows why they are the heir apparent to William Shatner, and upload it at http://shatner.blip.tv/ by September 30th.
