The Emmy Award-winning HBO drama “Succession” has become one of the most talked-about programs on television.

Upon seeing Culkin’s audition, “Succession” creator Jesse Armstrong knew he was perfect for the part.

“It’s just extraordinarily comforting to see somebody do it ‘right.’

Aside from revealing his “Succession” origin story, Culkin shared his favorite scene partner.

Though Snook, who plays Culkin’s on-screen sister, Siobhan, takes the top spot.

“I guess because my brother’s wife is Sarah.

So she’s Sarah.

Plus, it’s f***ing Snook.

Who else is named Snook?

It’s actually pronounced Snook.

But I can’t even get my head around that.”

Aside from his admiration for her name, Culkin loves Snook’s personality.

He proclaimed the 33-year-old the most beloved person on set.

Culkin also enjoys improving scenes with the Australian actress.

It’s just the most fun sibling dynamic on the set.

We get to play around and be cruel to each other as our characters.
