Lean Headey, who plays the titular heroinne, was out doing press for "300" recently (she plays the film's one major female role) and confirmed the casting to Sci-Fi Wire.
She added that one model would be good and one bad, but didn't point out which one is which. She confirmed they had just finished shooting the pilot in New Mexico which follows Sarah and her son John (Thomas Dekker) having made it to Los Angeles after the events of the second film "Terminator 2: Judgement Day".
Glau is best known for her work on the defunct but acclaimed Joss Whedon sci-fi series "Firefly" and its film spin-off "Serenity". She's also guest starred on "CSI," "Cold Case," "Angel," and "The 4400".
6'3 Welsh actor Yeoman has been a regular in several now defunct television series in recent years including 2004's "Commando Nanny", 2005's "Kitchen Confidential" and 2006's "The Nine" . He's also appeared in small roles in the films "Troy" and "Beerfest"
