It has home-invasion elements and is definitely a thriller, Aronofsky allows.

It is closer toBlack Swanin spirit than anything I have done in a while.

(Its rare and a luxury, says the director.)

Bardem had been following Aronofskys career closely since his 1998 debut,Pi.

I remember so well seeing that movie, says Bardem.

It blew me away.

AndRequiem for a Dreamwas the same.

I just remember she was so young and she was so funny!

She was making jokes about the show, about everything, we all were laughing a lot.

She is one of a kind and I truly admire her.

Did he ever think hed one day be playing her on-screen husband?

Bardem bursts out laughing.

Not even when I was shooting could I really imagine it.

In the scene above, the couple hosts a large gathering at their house.

Shes exceptional, says Aronofsky.

Its a very brave and bold performance.

She brought her A-game.)

But what is, you know, actuallyhappening?

The best thing about this film will be the surprise of it, Aronofsky insists.

Its an intense journey and its definitely the biggest roller coaster in the park.

Only get on it if you really want to do the loop-the-loop.

Bardem agrees with the vow of silence.

We all know every fing thing all the time, he says.

Thats good for some things and bad for others.

We have to keep this mystery going if we can.
