Adam Sandler's "Hotel Transylvania" previews at Comic-Con

(CBS/AP) "Twilight" isn't the only vampire film at Comic-Con this year, Adam Sandler's new animated comedy "Hotel Transylvania" is biting audiences, too.

Sony Pictures previewed footage of "Hotel Transylvania" in which Sandler provides the voice of the grand-daddy of vampires, Dracula.

It's the follow-up to a rare flop for Sandler, whose string of hits came to an end this summer with the dud "That's My Boy," co-starring Andy Samberg.

Opening Sept. 28, "Hotel Transylvania" again co-stars Samberg, who provides the voice of a human falling for Dracula's vampire daughter.

"Hotel Transylvania" director Genndy Tartakovsky says he's not worried that Sandler and Samberg are coming off a flop. The filmmaker says his PG-rated family tale is wildly different from the R-rated "That's My Boy."

"Movies go up and down, and I don't think there's ever been a history of one movie flopping and then a career ending for that person," Tartakovsky said in an interview. "There are a lot of rebounds to this business.

"And our film's for a different audience, so we weren't worried either way. Our movie stands alone, really well on its own, and it's Dracula with Adam's voice. It's a family film."

The voice cast also ncludes Selena Gomez, Kevin James, Steve Buscemi, Jon Lovitz, David Spade, Cee Lo Green and Molly Shannon.
