Very good movie! Too fun and featuring a cast of some very fun people.
Some of my favorites:
Zachary Quinto from Heroes, which I plan to start watching as soon as they are done with the series.
Simon Pegg (as Scotty) from Hot Fuzz.
Zoë Saldana from Pirates of the Caribbean (as Uhura)
and of course: Jennifer Morrison from House as Kirk's mother.
And what is up with Winona Ryder as Spock's mother? She had way too much makeup.
Silly me, I didn't even recognize Eric Bana!
