BOARDWALK EMPIRE
HBO, 9:00 p.m. ET
You’d think James Cromwell would be causing enough trouble on TV these days as the heartless doctor on FX’s American Horror Story: Asylum. But even though he’s a regular there, the actor had enough time to also pop in on last week’s Boardwalk Empire episode, playing the wealthy and imposing Andrew Mellon (James Cromwell) in an episode that, like at least one other prime-time drama last Sunday, featured the sudden death of a beloved supporting character.
