Best song ever? I don't know, but this video broke the VEVO record for most views within 24 hours of release with 10.9 million views. Pure One Direction... they are sooo cool :)

And believe me... Harry Styles takes on the role of Marcel the marketing geek, Liam Payne is Leeroy the choreographer and Louis Tomlinson plays Jonny, the first of two studio execs. Niall Horan is a second studio executive called Harvey, while Zayn Malik makes the most striking transformation as Veronica the sexy assistant.

- So I said to her, Angelina I want to, I really, really want to. But, what about Brad? Brad's like a son to me.
- You're a good man.
- I know, I know.
- Come in.
- One Direction are here to see you.
- Who?
- One Direction, they're making their new movie, shall I send them in?
- Sure, I love new movies!
- They're here, the real movie stars!
- The biggest band on the planet!
- Alright, they are! I love "The Direction", come on in guys, take a seat.
- Can I just say what huge fans we are of you guys?
- Huge! Nial, Louis, Liam, Harry, Zack.
- It's Zayn
- Sure, whatever you say, big guy.
- We cannot wait for this movie, it's going to be the greatest movie of all time. I'm talking academy awards.
- Emmys, Baftas.
- Have you ever seen Forrest Gump?
- Sure.
- Better than that!
- Have you seen The Hangover?
- Yeah.
- Funnier than that!
- Have you seen Titanic?
- Of course.
- Sadder than that!
- Sounds OK.
- It's better than OK, Zack, it's award-winning.
- We want to introduce you to our marketing guy, Marcel, Marcel!
- Hi.
- Here he is, he's going to run you through some thoughts on the new movie.
- Really nice to meet you guys, I'm a huge fan. Cute as a button, every single one of you.
- First scene, I'm talking massive dance number, I'm thinking a hundred dancers, fireworks, the lot. Dance is just so hot right now.
- Hey, you know I used to be a dancer?
- Really? what kind?
- Mainly tap.
- You've got the shape for that
- I want you to meet Leeroy, he's going to be your choreographer. Leeroy!
- Hi boys!
- Ok, so here's what I'm thinking. First open number is going to be really big, stay with me because I'm quite quick. And five, six, seven, eight...and Niall, for the shimmy, for the shimmy, and Zayn, pirouette, and Louis, do the splits, and Liam, you stay exactly where you are, because you are perfect.
- We'd never do that.
- Oh.
- So that's something for us to work on, thanks Leeroy. So let's take a look at some of the styling options for the film. Now, personally, I think this one is the one.
- Absolutely not.
- We'd never wear that.
- Right, how about this one?
- No.
- It tested really well.
- Never in a million years.
- Ta da...

Maybe it's the way she walked
Straight into my heart and stole it
Through the doors and past the guards
Just like she already owned it

I said "Can you give it back to me?"
She said "Never in your wildest dreams"

And we danced all night to the best song ever
We knew every line now I can't remember
How it goes but I know that I won't forget her
Because we danced all night
To the best song ever

I think it went, oh, oh, oh
I think it went, yeah, yeah, yeah
I think it goes...

Said her name was Georgia Rose
And her daddy was a dentist
Said I had a dirty mouth
-I got a dirty mouth-
But she kissed me like she meant it

I said "Can I take you home with me?"
She said "Never in your wildest dreams"

And we danced all night to the best song ever
We knew every line now I can't remember
How it goes but I know that I won't forget her
Because we danced all night
To the best song ever

I think it went, oh, oh, oh
I think it went, yeah, yeah, yeah
I think it goes...

You know I know you know I remember you
And I know you know I know you'll remember me
You know I know you know I remember you
And I know you know I hope you'll remember
How we danced
How we danced

-One, two, one, two, three-
How we danced all night
To the best song ever
We knew every line now I can't remember
How it goes but I know that I won't forget her
Because we danced all night
To the best song ever

And we danced all night to the best song ever
We knew every line now I can't remember
How it goes but I know that I won't forget her
Because we danced all night
To the best song ever

I think it went, oh, oh, oh
I think it went, yeah, yeah, yeah
I think it goes...

Best song ever
It was the best song ever
It was the best song ever
