with Miriam's potty mouth, because...

Or are you? You were in Harry Potter, but did you actually work together?

Yeah. Oh, yes, we did. Yeah, yeah, yeah, absolutely.

But I don't remember. I've been told there was a swear jar involved on set,

but I can't remember that.

I don't really remember you swearing a lot in front of...

I was probably careful when it was you,

but, you know, with the other kids I didn't bother.

LAUGHTER

He's the lead.

I was just talking backstage,

if that's what you call that funny, little...

..grubby area. All right, Miriam.

LAUGHTER

Apparently, it's 20 years

since Harry Potter came out.

Since we started filming the first one.

And your balls have dropped since then, I can tell you that.

LAUGHTER

It's a... It's a relief for us all.

I hope so.

Yeah, because they were just wee kids then.

We get it, yes.

It's just... Yeah.

It's interesting because Professor Sprout,

which, you know, you were in the second film and the last film?

Yeah, I should have been in all of them. Yes.

And that was a grave oversight and I'm holding you responsible.

I told them!

But, anyway, it was wonderful to be in the two that I was in

and I'm very proud of it.

But you do get recognised as Professor Sprout?

I do. I mean, I think I've changed since then

but people do recognise me.

And, funnily enough, in Lithuania...

SECTION OF AUDIENCE: Woo!

Lithuania. Are you from Lithuania?

Have you come just to see Professor Sprout?

I don't think so.

Oh, the film's called Professor Sprout And The Deathly Hallows.

No, but I was mobbed in Lithuania,

maybe because I was Jewish, I don't know. I'm the only one left.

Sorry.

Stopped cheering now.

But I just think that's incredible. You are being mobbed in Lithuania and you were Professor Sprout.

Imagine being this man.

I know, what was it like?

I mean, it's weird and funny

and I think the best way to see it always

was like weird and funny cos it will... You know, it ebbs and flows

and sometimes it's in your life a lot and sometimes it's not

in terms of getting recognised.

And there have been lots of very odd moments.

I was chased out of a science museum in Spain.

But it was sort of fine because everything was in Spanish there

and I couldn't understand anything inside,

so it was time to leave anyway. Yes.

Um, so, yeah.

But someone thought you were something else in New York recently.

Oh, yeah.

Tell it, tell it. You know what, actually, this did not come up...

Yeah, so...

So me and my girlfriend fostered a dog

and we sort of got our friends to adopt it.

This is unnecessary for the story. There's a dog with me.

I was on the street with this dog

and my girlfriend was in this shop and it was very cold.

Hoodie. I've got my hoodie and my fleece, my fleece hoodie,

and then a big coat over that

and the dog was really cold, so I was like, "I'll just kneel by you

"and stroke you and try and keep you warm."

And then I saw this guy look up at me like ten yards away

and smile and I was like, "Yeah,"

and just carried on.

And then he walked past me and he came back,

he got about five steps past me and then reappeared with a $5 bill

over my shoulder and just went, "Get yourself a coffee, mate."

Oh! LAUGHTER

My girlfriend came out and I was like,

"I don't think I'm dressed..."

I'm wearing nice clothes, I thought.

Yeah, so I was very...

That was a wake-up call. Apparently, I have to maybe shave more often.

Was your dog on a string?

It was not.

I do maintain - because the person that owns the dog

has also been mistaken for a homeless person with this dog -

I think the dog just looks very cold and sweet and vulnerable.

Don't blame the dog. No, no.
