Jesse Armstrong had to remind even Matthew Macfadyen that Tom Wambsgans isn't dumb
Sometimes the Succession star was inclined (like the rest of us) to forget that his loveably awkward Tom was capable of running a billion-dollar department

Unless you’ve been living under a rock these past few months (or you’re more of a Billions stan), you’re probably more than aware that Succession’s fourth and final season begins this Sunday—bringing, hopefully, a whole slew of long-awaited answers with it. Who, in the end, will take over the company? Will Roman finally get to kiss the tall man of his dreams? And will Tom wise up and hold onto his current power position? Or fumble it like he largely has thus far?
Taking on this last one has been a doozy for even Tom’s actor Matthew Macfadyen, who—like the rest of us—has sometimes been inclined to mistake Tom’s, well, extreme doormat-ness for outright idiocy. “Jesse [Armstrong, Succession’s creator] will remind Nick [Braun] and me, ‘He’s running a billion-dollar wing of this company; he’s not a total moron,’” Macfadyen said in a recent New York Times interview.
