The screening tickets are $10.00, and are available for purchase through Fandango only (with pick up at the theater prior to the event). The screening event will take place at the Pacific Gaslamp, 701 5th Avenue (a few blocks from the convention center), with the doors opening at 5:30 p.m. (Note: only two tickets are allowed per person).
Other special events taking place at Comic-Con through Summit Entertainment (their booth being in the Grand Hall) are an opportunity to have a photo taken in an exclusive The Twilight Saga: New Moon photo booth, the chance to collect special edition trading cards for the film, and the opportunity to meet the CG-enhanced animated versions of classic characters brought to life in Astro Boy. There will also be a spin-wheel where fans can win promotional give-aways and exclusive prizes.
