The cast for Star Trek X! is becoming firmer with each passing day. Today's news is that actor Anton Yelchin (Alpha Dog) is in final negotiations to play Pavel Chekov, the Russian-born navigator on the Enterprise. Yelchin will be starring in the high-school drama Charlie Bartlett later this summer, as well, so people will be able to get a good look at him before he gets to the Trek universe.
Now, Spock and Chekov are cast, and Abrams is casting a wide net to cast Bones, Kirk, Uhura, Sulu, Scotty, and other key roles. Those announcements are expected over the course of the next couple of months. The film will begin shooting soon, and is expected to be released on Christmas Day, 2008.
