Kieran Culkin annoys Succession co-star Brian Cox with ability to learn lines 'incredibly

During an appearance on The Late Show with Stephen Colbert on Wednesday night the actor, who plays Roman Roy in the hit HBO show, explained that the main skill he learned as a child appearing in commercials was being able to pick up dialogue very quickly. However, Kieran revealed that Brian, who plays his onscreen father Logan Roy, isn't so impressed by his "party trick"."I learn lines incredibly fast now because I've just been doing it since I was six. It's almost like a fun party trick. It p**sed off Brian Cox one day.
