Jason Bateman or Paul Rudd
Until recently with the Breaking Bad-esque like show Ozark in Netflix, not that he didn't show signs or a few hints here and there of his range as a dramatic actor, Bateman sort of played comedy-drama roles or occasionally drama TV or movie roles that sometimes got serious but weren't overly dark. Ozark is probably the darkest, least morally/ethically redeemable show he starred in, it's not just him by Season 3 if you've read Ozark Season 3 EE thread his wife is actually worse then he is and his son, Jonah, has all the signs of a future amoral sociopath who works on Wall Street and spree kills in his off-hours. Another American Psycho in the making.
Ozark may be the show that ends of defining Bateman's career, just like Bryan Cranston did with Walter White in Breaking Bad. It's that TV or movie role that if an actor/actress is lucky, his performances will make him legendary and will be talked about, discussed, analyzed long after he's retired or dead. Harrison Ford has several different movie roles of a lifetime that no one will ever just call him Han Solo, or Robert De Niro will be called just Don Corleone, or Travis Bibble(whatever his Oscar-winning role character's name was in Taxi Driver) or Meryl Streep for that matter.
Decent actors/actresses either star in or appear in some or a majority of Good shows than mediocre ones, good actors/actresses star or appear in a lot of good movies/TV series, and the great legendary ones like Daniel Day-Lewis make every movie they star in epic, whether it's the Gangs of New York, There Will Be Blood, Lincoln, or Phantom Thread. Day Lewis brought so much intensity, dedication, focus to his craft in his pursuit of excellence that he made other actors in his films better because of it. That ability of radiance that one actors brilliance, and intelligence makes him so good he makes other actors/actresses come off better is a rare gift, and not many Hollywood screen legends had it if you look at the industry's long history.
Bateman is a very good actor in those list of categories mentioned above, but he has the potential to be even better. Paul Rudd is a decent actor who maybe at his very best could be a good actor, but that's all.
