When does Northern Exposure return?

The series was created by Joshua Brand and John Falsey, who also created the award-winning shows St. Elsewhere and I'll Fly Away. Rob Morrow starred as New York City native Dr. Joel Fleischman, whose med school tuition was underwritten by the government of Alaska in exchange for him practicing medicine for four years in the state. Morrow left the show midway through its final season due to a contract dispute.
