Here’s a first. While studios choose different venues to launch movie trailers online, Universal’s teaser trailer for Fast Five will make its debut on the Facebook page of the film’s star, Vin Diesel. Diesel has developed a following of about 20 million fans, putting him in the top five celebrities who have sites. After Diesel posts the teaser on http://www.facebook.com/VinDiesel, other cast members who have active social media platforms–including Paul Walker and Dwayne Johnson–will post their teaser on their sites. I will probably pull it off Youtube. It will be up within the hour.
