Twi-hards, as they have been dubbed, have snapped up more than 1300 tickets to Greater Union Glendale's five 12am sessions of The Twilight Saga: New Moon, the second instalment in the brooding teen franchise based on US author Stephenie Meyer's novels.

Scotty's Cinema Centre at Raymond Terrace, Reading Maitland and Hoyts Charlestown will also have midnight screenings.

Many of these first New Moon showings are double bills, with the original Twilight screening before the clock ticks over to midnight.

Glendale cinema general manager Garth Weiley said New Moon was on track to outdo even Harry Potter movies for ticket pre-sales.

Glendale had only "a hundred or so tickets" left to its midnight screenings, mostly front-row seats.

"The breakfast sessions at 6am and 8am are also popular and we are considering adding a 2.30am session," Mr Weiley said.

Teenage girls made up the overwhelming majority of pre-sales.

"It's a modern-day Romeo and Juliet with a vampire twist," Mr Weiley said.

"But there are a lot of mums who will come quite willingly with their daughters."

As these recently released New Moon images reveal, heart-throb Robert Pattinson, who plays the brooding vampire Edward Cullen, has a rival for the affections of his teen sweetheart, Bella (Kristen Stewart).

Taylor Lautner plays the hunky werewolf Jacob, who comes between the lovers.
