"Fantastic Beasts: The Crimes of Grindelwald."

Were you into magic as a kid at all?

-I was -- I was properly --

I was sort of embarrassingly into magic as a kid.

'Cause I -- you know how kids

have magicians for their birthday and stuff?

-Yeah. -But normally until about the age of 8,

9 may be pushing it, 10, 11. -Yeah.

-At age 15, 18, no one came to the parties,

but I still had -- I was still inviting magicians, so...

-Really? -Yeah, yeah, properly in to it.

-I remember getting books out of the library

that were just magic trick books.

I think they technically counted as books,

so I was reading -- I was reading books.

-A proper book. -Yeah, exactly.

-I had a little brother

who was about six years younger than me,

so it was the perfect audience.

I could do magic tricks on him.

I tried ventriloquism.

And he got to about the age of well, 3, being able to speak,

and he was like, "I can see your mouth is moving."

-"Yeah, I'm not going to do that."

-No. So that was the end of my --

-But do you remember any tricks?

-I can do a trick for you, Jimmy.

-Yes. -I can try.

-All right, this will be fantastic.

All right, here we go.

-Okay. I need a --

-Oh, wow, here we go. Sure, yeah.

-I basically -- I basically wore a roll neck

because I feel like only magicians

can pull off roll necks.

And, like, so -- Okay, so here in this pocket here...

-Okay. -Not in that pocket. In this pocket.

...I have a special something for you, Jimmy.

And it's a letter with your name written on it

in really, like, Hogwartsian writing.

-Yes, it is. -I just want you to hold that.

I want you to hold that. Just keep that, look at that.

Hold it. Don't touch it. Just look at it.

Okay. Next out, what do I have in my --

Oh, here, I have a pack of cards.

-Okay. -Not any cards.

Actually, Jimmy Fallon brand cards.

-Oh, yeah. We do have our own kind of -- we have our --

-You have your own brand of cards!

That's the greatest thing ever!

Okay. -Isn't that awesome?

-So I'm going to take these cards out.

And because they're your own brand,

you know that there's nothing dodgy about these cards.

-These are, like, professional. These are the best cards you can get.

-In the world. Okay, good. -Yes.

-So, I'm just gonna -- I'm gonna basically take these cards.

I'm gonna rifle through them.

And I want to you shout "stop" when you feel like it.

-Okay. -Okay. But you have to shout it.

Okay? Ready, steady, go.

-Stop! -Okay, I want you to look at that card.

-Yes. -Can you see the card, Jimmy?

-Yes, I can. -Can you guys?

Can the camera see the card? -Yes.

-Okay, okay, okay. I want you to remember that card.

Can you see the card? Okay, good.

Now, can you help me?

-Okay, of course. -Remember that spell we just learned?

-Yes. -Can you lick --

[ Laughter ]

I want you to lick this.

I'm going to try to make the card disappear,

and I need your spittle, Fallon.

[ Laughter ]

-Oh, my gosh. I knew something was coming up with that.

All right, so you want me to lick this?

-I just want to try and make that card disappear.

But I need you to kind of think of the card,

and I need to you lick the pack of cards.

And my hands might vibrate as it happens.

[ Laughter ]

-Okay. -Okay.

Okay, good work. Let's see if it's gone, okay?

So can you see your card here, anywhere there, Jimmy?

-No. -Okay.

A little flourish. -Wow, yeah.

-Can you see your card there, anywhere here?

-No, I can't.

-No!

This has nothing to do with the trick.

I just love doing it.

Anywhere there?

-Bizarre. No.

-No, no, Jimmy, well, no,

because I have a potion in my roll neck

that I brought from Hogwarts, all the way.

And it is made --

This is crushed powder made with Niffler feces.

-Wow.

-That was a bit much, wasn't it? -It was a bit much.

Yeah, yeah, but still, it's good. I like it.

Enjoying this. -You see, there's nothing in my hand.

-Yes. There's nothing in your hand.

-So I'm going to take this excrement here.

-Yes. Be careful with that. -And I'm going to gently

just pour that over my hand.

-I hope I don't have to lick this.

-Well...

-Here we go. -Okay.

[ Blows ]

-Hmm.

-Think of your card, Jimmy. -No.

Whoa, look at that!

Seven of diamonds.

[ Cheers and applause ]

There's more. There's more! -There's more, there's more,

there's more, because look in your envelope.

[ Drumroll ]

-This is what I think it is...

Wow, it's wax. -It's waxed.

-Wow! -It could be an invitation to Hogwarts.

That might be slightly more exciting than what it is.

-Dude, you did it, man.

Oh, my gosh! Look at that!

Look at that! You see it?

[ Cheers and applause ]

You know what you're doing! You know what you're doing!

Eddie Redmayne, everybody!
