Urban, who is best-known for his roles in "The Bourne Supremacy" and "The Lord of the Rings" trilogy, will play the Starship Enterprise's medical officer.
Actor Chris Pine has also closed his deal to star as the young Capt. James Kirk after choosing to drop out of George Clooney's new movie, "White Jazz," because the two projects overlapped.
Leonard Nimoy, who originated the role of Spock and played him both on television and in films, will also be part of the latest installment, which is slated to shoot from November through March.
