Star Trek: Phase II (formerly known as Star Trek: New Voyages) is a fan-created science fiction series set in the Star Trek universe. The series was created by James Cawley.
The series, released exclusively via the Internet, is designed as a continuation of the original Star Trek, beginning in the fifth and final year of the Starship Enterprise’s “five-year mission.”
Star Trek: Phase II stars James Cawley in early episodes and Brian Gross in later episodes as Captain Kirk, Brandon Stacy as Mr. Spock, and John Kelley as Dr. McCoy. Eugene Roddenberry Jr., the son of Star Trek creator Gene Roddenberry, serves as consulting producer.
Some of the original actors have returned to reprise their roles, including George Takei as Sulu in “World Enough and Time”, and Walter Koenig as Chekov in “To Serve All My Days”.
