HOLLYWOOD, California — Hundreds of people were bitten by "Twilight" mania Friday night, as the immense Hollywood & Highland complex was overtaken by shrieking fans of the vampire series. After word spread that star Ashley Greene had chosen to celebrate the film's DVD release with an appearance at the mall's Hot Topic store, Twilighters began lining up mid-afternoon. By midnight, chants of "Ashley! Ashley" were filling the night air, and only discs full of bonus features could quench the thirst of the grinning mob.
