Chris Pine, who had been in talks to join the cast of J.J. Abrams' "Star Trek" flick, will play the young James Kirk, while Karl Urban will take on the role of Dr. Leonard McCoy, Paramount says.
Leonard Nimoy, who played Enterprise science officer Spock in the 1960s TV series and six "Star Trek" feature films, also will appear as an older version of the Vulcan.
Eric Bana, the star of Steven Spielberg's "Munich" and Ang Lee's "Hulk," is playing a villain in the "Trek" film, which begins shooting in November and is due out in December 2008.
Elsewhere, Spike Lee has begun production at Rome's famed Cinecitta movie studios on "Miracle at St. Anna," a fact-based World War II drama whose stars include James Gandolfini, John Leguizamo, Derek Luke, Michael Ealy, Omar Benson Miller and Laz Alonso.
Adapted from the book of the same name by its author, James McBride, "Miracle at St. Anna" tells the story of four members of the all-black 92nd Army division trapped behind enemy lines in an Italian village who battle besieging Nazi troops with help from the locals.
The film is scheduled for release in 2009.
