# List of Star Trek: Enterprise cast members

Star Trek: Enterprise is an American science fiction television series that debuted on UPN on September 26, 2001, and ran for four seasons until May 13, 2005. The show was the fifth live-action series in the Star Trek franchise, and was intended to serve as a prequel to Star Trek: The Original Series. It was originally entitled Enterprise, but was renamed to add the Star Trek prefix towards the start of the third season. The series was created by Rick Berman and Brannon Braga, both of whom served as executive producers throughout the four seasons. They stood down as show runners during the fourth season, with Manny Coto taking on the role instead.
The casting team pursued Scott Bakula for the role of Jonathan Archer, with no other actors in mind. There were extended contract negotiations, and Bakula signed up for another pilot during the talks which didn't go to series, and he instead signed for Enterprise. Both Anthony Montgomery and Dominic Keating had previously auditioned for roles on Star Trek: Voyager and were hired when they returned for Enterprise. Braga later explained that the most difficult casting process was for the role of T'Pol, who had been originally envisioned as the character T'Pau from The Original Series episode "Amok Time". Jolene Blalock was cast after attending the final casting session, after her agents had previously rejected invitations to attend auditions.
Some recurring characters were played by actors who had previously appeared in the franchise, with Jeffrey Combs portraying the Andorian Shran, making his first appearance in the season one episode "The Andorian Incident". He had previously portrayed the characters Weyoun and Brunt on Deep Space Nine. Vaughn Armstrong, who played Admiral Maxwell Forrest in Enterprise, had previously appeared in a number of roles throughout the franchise since portraying a Klingon in The Next Generation episode "Heart of Glory" and by the end of the Enterprise run, he had appeared as 13 different characters in total. Randy Oglesby, Rick Worthy and Scott MacDonald had also appeared in a variety of parts within the franchise before taking on the recurring parts of Xindi council members throughout the third season.
