Later in their conversation, Kmetko asked Roberts about his favorite performers.

Rather than cite any particular influences or heroes, the actor instead used the opportunity to praise his daughter.

I’m so proud of her I can’t see straight.

Here she goes again.

Except I gave her that name.

It was just fun to be associated with that movie, he said.

[Christopher Nolan] is a real director, and he knows what he wants.

So it was a real pleasure for me to be told that.

Want more movie news?

Roberts also said thatHeath Ledgerwas a pleasure to work with.

What a lovely person he was, Roberts said.

I’d been told, Stay away from Heath.

He’s into the character.

Oh, my God.

He wasn’t like that at all.

He was perfectly fine.

He’s going through the monologue, blah blah blah, and he gets to the monologue.

And he’s done with the monologue, and he’s done.

And he turns to us and he goes, How am I doing?

He’s just so charming, so likable, so sweet, so normal.

And all the stuff that I heard about him was not true.

And he was a lovely person.

He was a real loss.
