LOS ANGELES, November 21 (UPI) -- Hundreds of Thursday midnight screenings of the vampire flick Twilight have been sold out in the United States, the ticket broker Fandango reported.

The company said theater owners are adding additional showtimes -- some as late as 2:45 a.m. Friday -- to meet the demand for tickets.

Based on the popular young-adult novel, Twilight has eclipsed both Harry Potter and the Goblet of Fire and Harry Potter and the Order of the Phoenix on Fandango's list of Top 10 Advance Ticket-Sellers -- taking the No. 3 spot and knocking Goblet down to No. 4 and Phoenix to No. 5.

Star Wars Episode III: Revenge of the Sith is No. 1, followed by The Dark Knight, Fandango.com said.

Twilight currently represents more than 94 percent of all weekly ticket sales on the Internet ticket broker's Web site.

"It's our fastest ticket-seller since The Dark Knight, Rick Butler, chief operating officer of Fandango, said in a statement. "The impressive advance ticket sales are clearly the result of the growing Internet buzz from the novel's online fans. There are so many moviegoers staying up late to see the movie at midnight that Twilight might single-handedly boost coffee sales on Friday morning."
