On tonight’s new installment, David Steinberg’s guests, there to discuss comedy, are comic actors from different generations – who, in other movies, also play serious roles. One is Jonah Hill, who’s gone from Superbad and Get Him to the Greek to Moneyball and The Wolf of Wall Street. The other is Alan Arkin, the Second City veteran whose movie career has encompassed everything from Wait Until Dark and Catch-22 to Little Miss Sunshine and Argo.
