The Twilight Saga: New Moon, Peter Jackson and James Cameron's Avatar may be among the highlights of this summer's Comic-Con International in San Diego, the New York Times reported today.

Jackson has never attended in person, despite having had many of his movies hyped at the show. But the director will appear in Hall H of the San Diego Convention Center in support of District 9, an alien-internment thriller set for release by Sony on Aug. 14.

Jackson produced the film, which was directed by his friend Neill Blomkamp, who will also attend.

Comic-Con is still finalizing its schedule, and it is entirely possible that Jackson could be upstaged by another science fiction heavyweight: James Cameron, who may bring his 3-D sci-fi epic Avatar. A Fox executive told the newspaper that the filmmaker was still deciding.

New Moon is Summit Entertainment's sequel to the hit Twilight.

Meanwhile, Warner Brothers will make presentations on about 10 films, although it has not fully determined the lineup. Comic-Con runs July 22-26.
