Macfadyen plays a British politician who faked his own death.
“And, yeah, there was the specter of jail for poor old Tom last season.
But that thankfully went away.”

The politician planned on starting a new life in Australia with his secretary.
“John Stonehouse was a very promising young MP in the Labour Party,” says Macfadyen.
“He was was a very personable, charismatic guy.
But then he got in over his head.
It all became too much and he decided to fake his own death.
He flies to Miami and then subsequently flies to Australia on a fake passport.
And we see we aftermath of that.”
TheSuccessionstar describes reteaming onscreen with Hawes as “lovely.”
“Very, very, very enjoyable indeed,” he says.
She sort of nails him."
Macfadyen himself underwent something of a retro makeover to portray Stonehouse.
“He had hilarious teeth.
Very ’70s English teeth.
In fact, his top teeth were a real horrorshow.
We didn’t do that, because it would be too much.”
Macfadyen is calling EW from New York, where he is shooting the fourth season ofSuccession.
“We’ve got another month or so,” he says.
So, can Macfadyen tease anything about the upcoming season?
“Not really, no,” he says with a laugh.
“I don’t know what to say about it.
It’s good, I hope!
I mean, who knows.
It’s been great fun to shoot.”
Stonehousepremieres on BritBox Jan. 17.
