Today, we can’t stop watching Matthew Macfadyen, who plays Tom Wambsgans, the awkward yet sympathetic husband of Shiv Roy, on HBO’s “Succession.” Macfadyen takes us behind the scenes of shooting the congressional hearing meltdown and stealing chicken from Logan Roy’s plate on the show. Plus, we hear about Macfadyen’s role on “Quiz,” the AMC mini-series about a couple who attempted to cheat on the British version of “Who Wants to be a Millionaire.”
