Finally, the critically lauded stars of 'Lone Star' have all found other gigs. Adrianne Palicki was cast yesterday in David E. Kelley's 'Wonder Woman' reboot, and now the other two leads have booked pilots of their own.

The charming James Wolk will play young speechwriter Andrew Pierce in Josh Schwartz and Stephanie Savage's Washington, D.C.–set ABC pilot, 'Georgetown.' According to Vulture, the casting breakdown describes the character as a "handsome, effortlessly charming, sophisticated, brilliant, Yale graduate" and "the youngest presidential speech-writer on record."

Eloise Mumford, who played Wolk's sweetly innocent girlfriend on 'Lone Star,' is the first one cast in the ABC thriller drama 'The River.' She'll star as a "fearless helicopter pilot" searching for a missing TV explorer and his cameraman (who also happens to be her father) in the Amazon, according to Deadline.
