On the Friday after Tom Wambsgans became the new puppet CEO of the Waystar-Royco media empire, the actor who has spent the past five years essaying the character’s ups, downs, and withering one-liners is propping up the bar of a small boutique hotel in London’s Chelsea. Matthew Macfadyen is nursing a lime tonic and contemplating a rest after several months of hard work on Succession’s blockbusting fourth season. In some other world, one imagines his fictional alter-ego is already discovering the poison in the chalice of the job he has spent a lifetime coveting. Macfadyen, instead, is content simply to think ahead to a quiet family dinner, and to reflect on the adventure of his past half decade.
