Spock is back! Nimoy to star in new Star Trek film

"This is really going to be a great movie. And I don't say things like that lightly," Nimoy told a gathering of 6,500 fans Thursday at Comic-Con, the nation's largest pop-culture convention.

He greeted the crowd with a Vulcan salute.

Nimoy was joined by the newly named young Spock, "Heroes" star Zachary Quinto, who bears an uncanny resemblance to Nimoy.

Both Spocks were introduced by the film's director and co-producer, J.J. Abrams.

Star Trek is bringing sexy back. And by that I mean a smoldering hot young Vulcan. Heroes star Zachary Quinto, who does bear an eerie resemblance to Leonard Nimoy, was announced as a young Spock in the next Star Trek movie. Nimoy is back, too, as older Spock. Young Captain Kirk, however, is still uncast. Resumes are now being accepted at the Starfleet Academy.

Quinto, who was also present, said he was excited about recreating the character of Spock with Nimoy's help and blessing. "It is pretty incredible to be part of something so iconic," Quinto said, "and to be doing with the support and involvement of the man who created the role is a true honor. I certainly intend to bring my own spin on it and working with these guys I am sure we will find that."
