"Professor Brian Cox"

SmartLess

August 3, 2026

Put on your thinking cap: it’s Professor Brian Cox. We travel the galaxies of chit-chat — from black holes and cage dancing to a thousand Einsteins and the building blocks of space and time. “You can’t make progress if you think you know everything.” Our thoughts exactly. Welcome to SmartLess.
Speakers: Jason Mantzoukas, Sean Hayes, Will Arnett, Brian Cox
**Jason Mantzoukas** (0:07)
I don't mean to bother you guys or anything, but about to start a podcast, I'd love a little help. I don't know if you guys are busy, but...

**Sean Hayes** (0:15)
No, I guess I could jump in. What's the podcast called?

**Jason Mantzoukas** (0:18)
Well, we just sit and talk and visit.

**Will Arnett** (0:20)
Yeah, what's it called? Oh, I love to visit.

**Jason Mantzoukas** (0:23)
Well, I'm not bright, right? So kind of, I'm thinking about Unsmart.

**Will Arnett** (0:29)
Oh, that's good.

**Jason Mantzoukas** (0:30)
But it doesn't really roll off the...

**Sean Hayes** (0:32)
Yeah.

**Jason Mantzoukas** (0:33)
I'm without Smarts, so I'm...

**Will Arnett** (0:36)
You don't have more Smarts.

**Jason Mantzoukas** (0:38)
No, I'm less than Smart. So what do you...

**Sean Hayes** (0:42)
Maybe dumbass.

**Jason Mantzoukas** (0:43)
Less Smart.

**Will Arnett** (0:44)
Let's come up with that later. Let's do the show. We'll come up with it later.
Great. Welcome to an all-new SmartLess.

**Jason Mantzoukas** (1:07)
Hey, Willie, did you just barely make it? Hold on. We have... He's not out of breath. Will Audio.

**Will Arnett** (1:12)
Do we have Will Audio? Will Audio. I made it. We got Will Audio.
I made it. I made it. I just ran out of the car. I made it. You guys, I made it. I was on the...

**Sean Hayes** (1:25)
You were on the freeway?

**Will Arnett** (1:26)
I was on the LIE, guys. I was on the LIE, just keeping it real.

**Sean Hayes** (1:30)
You know, you're lying.

**Jason Mantzoukas** (1:31)
Did you ever see that movie, by the way? LIE with Brian Cox plays like a child molester. Incredible movie.

**Sean Hayes** (1:38)
What?

**Will Arnett** (1:38)
I know I didn't see it, man.

**Jason Mantzoukas** (1:39)
I didn't want to start with that, but...

**Will Arnett** (1:41)
Wait, what are you talking about? Well, let's bring it down for sure. It's some horrible story. Let's talk about it.

**Sean Hayes** (1:46)
When did that come out?

**Jason Mantzoukas** (1:47)
Oh, 20 years ago, I'll bet.

**Sean Hayes** (1:49)
Okay.

**Will Arnett** (1:51)
Seanny, I just narrowly missed seeing JB this morning. I'm so sad.

**Sean Hayes** (1:55)
Oh, are you guys okay?

**Will Arnett** (1:56)
And last night, because he was working last night. He's working splits. Now, tell Tracy what a split is, Sean.

**Jason Mantzoukas** (2:03)
We take a banana, and Jason.

**Sean Hayes** (2:05)
I'm in.

**Will Arnett** (2:06)
Jason.

**Jason Mantzoukas** (2:07)
A split is like when you start at noon, and then you end at midnight. So you can shoot some day scenes and some night scenes all in the same 12 hours of work.

**Will Arnett** (2:17)
And it's kind of fun because you can avoid, you can avoid a full night shoot, which everybody dislikes.

**Jason Mantzoukas** (2:23)
Yeah, it's not, it's not.

**Will Arnett** (2:25)
And at our age, doing a night shoot.

**Sean Hayes** (2:27)
Also, it's summer because so the light is, it takes a long time to get dark.

**Will Arnett** (2:32)
Oh, explain that to us.

**Jason Mantzoukas** (2:33)
You have a short, you don't have a lot of night hours. So it's not ideal.

**Will Arnett** (2:37)
Sean. Yeah, Sean. Hi.

**Sean Hayes** (2:39)
How's everybody doing?

**Will Arnett** (2:40)
It's so good. We haven't seen each other in a long time. I know, I mean, I FaceTimed you a few days ago, but it's been a minute.

**Sean Hayes** (2:46)
A minute. And Jay's working his balls off.

**Will Arnett** (2:49)
Jay's worked, he worked them right. I heard he worked them clear off.

**Jason Mantzoukas** (2:52)
Yeah, I gelded myself yesterday.

**Will Arnett** (2:55)
Oh no. How was the first week, JB.?

**Jason Mantzoukas** (3:01)
Really, really good. I'm very, very happy. It was hard, it's a lot of work, god damn.

**Will Arnett** (3:07)
Yeah, it is.

**Sean Hayes** (3:08)
I mean, how long are the days? Like 12 hours?

**Jason Mantzoukas** (3:10)
They're 12 hour days, but like, you know, you'd like, you raise your hand for the position of supposedly having the answers to everything. It means you gotta try to think about everything.

**Sean Hayes** (3:20)
And everybody looks at you.

**Will Arnett** (3:21)
Everybody looks at you like, what's next?

**Jason Mantzoukas** (3:23)
Yeah, you can't just sit in your trailer and wait for them to say, okay, we're done, we're ready for you, come on, come speak.

**Will Arnett** (3:28)
Right, right, isn't that nice?

**Sean Hayes** (3:30)
I know, actors have it nice.
I went to my niece's wedding, Laura, in Iowa. I've never been to Iowa.

**Jason Mantzoukas** (3:37)
Wait a second, I've never been to Iowa.

**Sean Hayes** (3:40)
