Prometheus: WonderCon Exclusive Trailer

This is a clip which was featured at WonderCon. ('WonderCon is an annual comic book, science fiction, and motion picture convention, held in the San Francisco Bay Area since 1987' Wikipedia) This would intruige the people at WonderCon (who have a clear love for films like Prometheus). This would be great advertising as alot of people go to WonderCon, and with the clip it intruiges the viewer to want to see more.
