Lexa Doig cast in V

After spending two years playing Dr. Carolyn Lam on Stargate SG-1, actress Lexa Doig is putting on the white lab coat again for another genre series.

TV Guide has reported the actress is joining the cast of the ABC network series V, playing an OB/GYN who will treat one of the series’ main characters.  That character found out she was pregnant in the November cliffhanger.

The V franchise has roots that go back to the original miniseries, which aired in 1983 on NBC.  The plot involved the arrival on Earth of a technologically advanced race known as the Visitors.  Although seeming to visit Earth for peaceful purposes, it becomes apparent quickly that the aliens have a sinister purpose.

After strong ratings, a sequel miniseries was produced followed by a weekly television series that ran for one season in 1985.  ABC brought the property back to television screens last year as a sweeps event, airing four episodes in November.

The remaining nine episodes of the season will air after the 2010 Winter Olympics in Vancouver — with the first scheduled to hit the airwaves on March 30.  Doig’s casting reunites her with fellow Stargate actress Morena Baccarin (“Adria”), who is a series regular.
