ENTERTAINMENT WEEKLY: What do you remember the most about Bill?CHLOE SEVIGNY: Obviously, himsmiling.

He was so jovial.

He was one of the less cynical, jaded people Ive ever met in the business.

Like, how did he keep up this boyish enthusiasm and charm for so long?

A good ole boy in a way.

Its really hard to make an impact in those big movies, with a small part.

He was just fearless.

I think its because he was so rooted, such a good person.

He was really exceptional.

Even just working with him for five years onBig Love.

He just went above and beyond.

And whenever he came to New York, he would invite me on these weird adventures.

We went to eat at that fancy place Daniel with some of his friends.

It shows the strength of his character and how exceptional he was.

The letters he would write, theyre so beautiful.

Im a huge fan of the singer Nico.

Just above and beyond.

He was already a staple in my mind as this great character actor.

Everybody could take that leap of faith with him.

It was pretty extraordinary.

He worked longer and harder than everybody else.

He was just so committed.

He would come in with a script marked, every episode.

You could barely see the lines, he had done so much work.

He worked really hard, put a lot of time into it.

He was really professional, positive, would let other people have their moments.

He was always so positive, and really loved the business, and loved creating.

That was really refreshing, and inspiring.

Especially going on five years on a show, it can drag a little.

He helped keep things in perspective, and remember what we were doing was important.

He believed in entertainment being transportive and transformative.

He believed in the magic of what we can bring to people.

That was really a gift that he gave to me.
