A lot of people call him the best.

That's it. He's just the best. Because he is.

He's an Emmy- and Golden Globe-winning actor

who stars in the new movie "Wild Mountain Thyme,"

which is in theaters and on demand this Friday.

Here is the one and only Jon Hamm!

Oh! -You know what?

-That's what I'm talk-- -I'll take it.

-That's what I'm talking -- -I'll take it.

-It's great to see you, buddy, as always.

-The best. This is the best.

-Yeah, no, I had to call you the best, because you really are.

Everyone I talk to,

they go, "Please, we love Jon Hamm. He's the --"

You are the best. -I'll take it. I'll take it.

-Last time you were on our show,

we were talking to each other from our homes.

It was seven months --

seven months ago. -Early pandemic.

-Now I'm in the studio.

But you were back on a film set. -By yourself.

I know. I was back on a film set in Detroit, Michigan,

during the election.

-Wow. -Which was very strange

to be in a battleground state

during an election, I will say that.

But also strange making a movie

where everybody has to be in masks

until three seconds before they start rolling the cameras.

-Oh, my gosh. -But we did it. We were safe.

Nobody got infected

or super-spread anything. -Is this the Soderbergh movie?

-Steve Soderbergh directed.

-Come on. -Cast including myself.

We had a Cheadle.

We had a Benicio del T.

-Oh.

-We had a Kieran Culkin. -[ Stammering ]

-For the younger viewers out there, we had a Noah Jupe.

-I would go to this party in two seconds.

-Had it been not on lockdown, you would have been invited.

-Oh, my gosh. Were you guys in a bubble somewhere?

-Yeah, we all stayed in the same hotel in downtown Detroit,

which by the way, Detroit, if you get a chance, go visit.

It's a very cool city.

I'd never been. My first time. And, yeah, it was super awesome.

-Oh, and they have great hot dogs there, by the way.

-Yeah, the Coney dogs, man.

I definitely -- I visited Lafayette Coney Dogs.

Free plug.

-Yeah, but I love that there's two --

-And you know they're right next to each other, exactly.

-Actually, the walls are touching, the two --

American might be the other one, right?

-Yeah, American and Lafayette, they share a wall.

-[ Laughs ] Competing Coney dogs.

-If you don't like hot dog here,

the exact same thing is right next door.

-Three seconds away is the exact same thing.

-Exactly. Just in case.

-It is not even Larry David. It's beyond.

It's not a spite -- -No, it's not a spite store.

Or it might be a spite store, but if it is,

it's going on for 70 years, so it's amazing.

-[ Laughs ] Oh, my gosh. How is Cheadle doing?

-Great. In fact, I went to Lafayette Coney Dogs

with Cheadle.

So it had to be a pretty out-of-body experience

for the, like, Greek man, who didn't care, by the way.

He was like, "How many hot dogs do you want?"

We were like, "Two each."

[ Both laugh ]

-That was -- Yeah, that was the highlight of --

He had no idea it was you guys. Didn't care.

He's like, "Yeah, we're good."

-Selling dogs.

-Speaking of dogs, you got a dog.

-I do. Where is he? Oh, I think he's hiding.

But, yeah, it's -- We got a puppy.

And by pup-- I'm using that very, very loosely,

because he goes about 65 pounds,

and he's 8 months old.

-Wait, how is he -- -He's going to be a chunk.

He's going to be a big chunk.

Let me see if I can actually -- -What kind of a dog?

Poodle? -It's half -- Yeah.

Half Rottweiler.

-80-pound Poodle.

-Murphy. [ Whistling, snapping fingers ]

Murphy, come. -Uh-oh.

-Alright. You ready? -Let me see this --

-This is Murphy.

-Ohh, it's a good puppy!

-Murphy! -That's a puppy.

Hi, Murph! [ Laughing ] Oh, my gosh.

He's a beast, dude. He's going to be big.

-I'm not kidding. I'm not kidding.

He is a large, large dog.

-Is this his TV debut?

-Yeah, it's his TV debut.

He immediately, by the way, left.

-Yeah. Of course.

-He is exactly like the Greek waiter at Lafayette Coney Dog.

Doesn't care. -He's like,

"Yeah, Jimmy Fallon --" -Got what he needed, came in,

got his toy, bailed.

-Yeah, out. Yeah. -Peace out.

-You know what I wanted to talk to you quickly about,

but we don't have to lay on the horn too much.

But our buddy Andy Samberg was on the show recently,

and we're talking, like,

"What shows you watching during quarantine?"

And he goes, "You know what I'm watching is 'Mad Men.'"

And I go, "What do you mean, 'Mad Men' with Hamm?"

He's like, "Yeah, I know. That's our friend, Jon Ha--"

I go, "You've never seen it?"

He goes, "I know it, I've seen,

but I've never watched the whole thing."

And he goes, "I just feel so bad.

because I don't know if -- We never really fake discussed it.

but he probably assumed that I saw it, and I just never --"

He goes, "But it's amazing."

I go, "Of course it's amazing. But it's like, he won Emmys.

We celebrated with him. Dude, like --"

-Yeah. You know, the funny thing was, like,

the first time I hosted "SNL,"

they all dressed up in "Mad Men" gear,

like, everybody.

And I was like, Samberg kind of half-assed it.

I was like, "What are you -- Who are you?

Like, you just put a tie on? What's the deal?"

Everybody else -- Like, Paula Pell taped a cigarette

to her thing and was in, like, a little pencil skirt.

And Hader was in drag as Joan.

Like, everybody else was sort of into it.

So I realized, like, when Samberg --

He texted me in like April or May.

And he's like, "I got to tell you, man,

I've been watching the show.

I am sort of embarrassed to admit it. I never saw it."

I was like, "Oh, don't be embarrassed,

but I'm glad you're enjoying it now."

It's better than getting a text like,

"Hey, I finally saw your show, and I don't get it, man.

I don't, uh --" -[ Laughs ]

That's so good.

Hey, I want to talk about your movie.

'cause you know I love a good rom-com,

and I do love a good love story,

and I love -- I'm Irish.

so I do love good shots of Ireland anytime I can see it.

"Wild Mountain Thyme," T-H-Y-M-E.

-Then, Jimmy, if you love those things,

this movie is for you.

-It was for me. I loved it.

Dude, I love Jamie. I love Emily.

I go, and then, I get Jon Hamm in there, as well.

I go, Christopher Walken?

-Hey -- Yeah, I'll up the ante.

How about a little Chris Walken for you?

-[ Stammers ] Come on.

How was it to hang out in Ireland with Christopher Walken?

-I will tell you the greatest story. I did not --

This is secondhand. This is from John Patrick Shanley,

the director and writer of the film.

But he would say Chris was so enamored of Ireland,

where he had never been his whole life --

It was his first time. My first time in Ireland,

his first time in Ireland --

that he would just sit in his room

and stare out the window at the cows,

and then he would make up stories

about what the cows were thinking.

-[ Chuckling ]

-Very, very detailed stories.

And let me tell you, they were not pleasant thoughts.

-Wow, interesting. -He was convinced

that the cows were very sinister and were probably up to no good.

And I was kind of like --

-You can't turn your brain off, man.

-No. I mean, that is peak Walken right there.

There's only one Chris Walken.

And any time you get to spend with him

is time that you just absolutely treasure.

I didn't have a lot of scenes with him,

but I got to spend a couple dinners with him.

And I would just find myself, like, smiling and nodding

and just having the greatest time.

Such a lovely man. -Just the air in Ireland.

Just everything, and you go -- Even if it's --

-Holy moly. And you know, like --

We shot every inch of it.

It's so lush and beautiful.

And we were there in September, October,

so it was kind of rainy.

But then it would just be, like, rainbows everywhere.

You're like, "Are you kidding me?

Like, come on, Ireland.

Like, we get it. We get it."

-"We get it." -"We don't need 40 rainbows

to, like, hammer the point."

It's a hat on a hat on a hat on a leprechaun on a hat

with a lucky charm and then like two more hats.

-It's the greatest. -Ah, it was so beautiful.

It was so beautiful.

-Do you want to set it up,

or did I set it up already just saying that it's a love story

and --

-It's the most beautiful, honest, sincere love story

without a trace of cynicism or snark,

and it's the perfect antidote to everything about 2020.

How's that? -Ah, I love it.

I want to show a clip. Here's Jon Hamm and Emily Blunt

in "Wild Mountain Thyme."

Take a look at this.

-I mean, I'm not so sure about love,

but marriage is a practical partnership --

who's gonna take out the trash, that kind of thing.

-What marriage?

-Do you want to be married?

-Is that a proposal?

-No.

I mean in general, do you want to be married?

-I suppose.

-Me, too.

Anthony, however, I don't think he's the marrying kind.

-How would you know? -Because you were right there.

You were right next door,

and nothing happened.

-I'm not next door now. -No, you are not.

And I find that very promising.

-More with Jon Hamm after the break.

Come on back, everybody!
