Jon Hamm and others discuss a 'super painful' (but 'satisfying') end to 'Mad Men' at TV press tour

PASADENA, CALIF. -- As usual, there's not much to reveal about the upcoming season of "Mad Men," the acclaimed and highly secretive AMC drama that returns Sunday, April 5, for its final seven episodes."There's no version of this ending that is not super painful for me," Jon Hamm, the show's star, told journalists at the Television Critics Association's winter press tour here Saturday morning.
