J.J. Abrams is wrapping up casting on his upcoming Star Trek feature film (see 'Bones and Kirk Set for New Trek Film'), and has added two new cast members.  Winona Ryder will play Spock's mother, according to Variety. 

And Bruce Greenwood will play Christopher Pike, the first captain of the Enterprise, according to Hollywood Reporter.  The casting of the Pike role fits with the storyline, which will tell the story of the early days of the Enterprise crew.  Greenwood is a veteran of such recent features as I, Robot, Eight Below, and Capote.
