Kieran Culkin Jokes 'I'm Just Making an Ass of Myself' as He Accepts a 2022 Critics Choice Award

Succession actor Kieran Culkin had some success when he took home the prize for best supporting actor in a drama series at the 27th Annual Critics Choice Awards on Sunday.

Culkin beat out his costars Nicholas Braun and Matthew Macfadyen, as well as Billy Crudup (The Morning Show), Justin Hartley (This Is Us) and Mandy Patinkin (The Good Fight) for the award.

The actor, 39, said he didn't prepare an acceptance speech but nonetheless made it a memorable moment.

"Lowered it, nice," he said of the microphone when he took the stage. "Wow, thanks. Shut up. Awful. I was just telling Jeremy [Strong] how I really hope they don't say my name. I was really looking forward to that relief of not having to say anything. I have not prepared anything so anything could come out. So I don't know what to say here."

"Thanks, Critics, wow," he continued. "I'm gonna say that Succession has just been a dream. It's like the dream job. I've been spoiled rotten. Jesse Armstrong is kind of a genius. All the writers on our show are just the best at what they do I feel like. And they give me so much to work with. All of our actors are so fantastic to work with. I love you, [Sarah] Snook. I love you so much, wish you could be here."

Culkin made sure to call out his costar J. Smith Cameron — with whom he shares an on-screen romance — as well.

"You too J., shut up," he said. "She hates when I single out Snook as someone that I love to work with so J., I'm going to tell you right now, I think you are probably my favorite actor to do scenes with after Sarah Snook."

The father of two proceeded to go over the correct pronunciation of Snook's last name and revealed that Macfadyen's name is David.

"I'm just dropping bombs here," Culkin quipped. "It's true, look it up. I'm just talking now. I'm just saying things, stuff. I'm gonna say thanks to Casey Bloys and Francesca, everyone at HBO. It's been fantastic working with you guys, like really. It's like I'm just dying up here right now."

He seemingly got a cue as he said, "So yeah. please wrap it up — you're right, I should've done that like 30 seconds ago. I should've walked up here, said, 'Thanks,' and then walked out 'cause now I'm just making an ass of myself. Yeah, thanks, you're never going to do this for me again. Thank you."

Succession premiered on HBO in 2018 and follows the Roy family as they prepare for the next phase of their media conglomerate, Waystar RoyCo, amid family patriarch Logan Roy (Brian Cox)'s declining health.

Culkin plays the youngest heir to the Waystar throne, Roman Roy — a role that earned him his first Emmy nomination in 2020 for outstanding supporting actor in a drama series, multiple Golden Globe nominations, a SAG nod, and now, his first Critics Choice Award.

Speaking about his character, the actor previously told Jimmy Fallon on an episode of The Tonight Show how he thinks audiences love to hate Roman.

"I'm not sure that they [viewers] like the characters, there's something about them they just want to watch them and maybe watch them fail or something," Culkin said, later noting, "I usually, when I do a job, I don't care what the perception of it is gonna be, because I'm just like, I did my part, however people like it is none of my business. Now I'm a little bit like, I hope people like it, because I wanna keep doing it."

"So the fact that like people have been liking the show it actually feels really nice," he added.

Succession — which also stars Strong, Alan Ruck, Snook, Cameron, Braun and Macfadyen — has released three seasons so far and was renewed for a fourth in October. Snook, 34, picked up the best supporting actress in a drama series honor.

The 27^th annual Critics Choice Awards are airing live on The CW and TBS from 7 to 10 p.m. ET/PT.
