A tale of two Spocks

It's officially official. Once again from AICN, here's Zachary Quinto and Leonard Nimoy together at Comic-Con for the announcement of his casting.

UPDATE: There are more photos from the presentation on StarTrek.com. That's where I also found an image of the new teaser poster.

In other news, the part of Captain Kirk has not been cast yet. There were rumors for quite a while about the role going to Matt Damon, but that's not going to happen.

J.J. Abrams confirmed that Nimoy will be appearing in the movie as old Spock.

Right now the script does not include an appearance by old Kirk. But Abrams said they would like to include Shatner somehow if they can figure out how to make it work with their story.

The release date for the movie will be Christmas Day 2008.
