FACES/PLACES

“Dallas” will have three new cast members for its 13th year on CBS. Kimberly Foster will be around to give J.R. fits, Sasha Mitchell will be a hunk of a man who may be J.R.’s son, and Michael Wilding, son of Elizabeth Taylor and the late British actor Michael Wilding, will be a powerful art gallery owner with more than a passing interest in J.R.’s wife.
