Horn, who has spent his days as an editor at Current TV since its launch in 2005 and also directs for San Francisco video shop Rehab, doesn’t have a beef against Trek, although he finds it contains more cheese than his favored Star Wars. He just likes to seamlessly mash up sci-fi legends.

Guy works at IGN now and made the video for them I guess.
