- I'm very lucky to work with great directors, you know?

Woody Allen and Steven Spielberg, and John Sturges, a great director, really fine filmmakers.

But I think I had the most in common with Sidney because we both actors.

- I'm sitting here with Treat Williams who was the star of, "Prince of the City," by Sidney Lumet.

Treat, thank you so much for joining us.

- Thank you.

It's an honor.

- Why don't we begin by talking about how you learned about, "Prince of the City."

I know you auditioned at great length and many times for that role, so tell us about that process.

- Well, I had auditioned for Sidney, interestingly, for, "Dog Day Afternoon," a couple years earlier.

So I think he was at least aware of me as one of the young actors in New York.

And then Miloa Forman cast me in, "Hair."

I was doing the musical, "Grease," on Broadway.

And I think Sidney saw something in that performance that, how he could apply a sixties hippie to an Italian cop coming up in the seventies.

I'm not sure, but I know he saw something in it.

And we started a very, very intense process.

His greatest concern was at my age, at that age, that I had the gravitas to play the latter parts of the film.

And that's what we worked on most.

- It's a kind of American tragedy.

It's a very dark film.

- It is, it is.

- And I went to some very dark places.

It was difficult to recover from.

He brings down the people he loved most, his partners.

- Yeah.

- There were suicides.

It was a terrible thing to see happen.

- Were you aware that Sidney was ambivalent about this character, your character, Danny Ciello?

- No, I wasn't thinking about Sidney's ambivalence.

(both laughing) I was worried about playing the biggest role I'd ever been given.

So what Sidney felt about it was less important to me than him helping me... - And tell us how he helped you.

How did he help you - Well, I gotta say, prepare for this?

this is for any film students who see this.

He rehearsed the film like a play.

First of all, he took me to all the locations and showed me what they actually looked like.

And we always used, almost always, real rooms in real places.

I think there were 160 speaking roles in the film.

And we hired a great hall on Second Avenue.

And he taped out every single set, and we blocked out every single scene.

We were rehearsing a play, a screenplay, but a play.

Sidney came from live television and that's how he worked.

And he did this wonderful thing.

We would, you know, we would get, once we got our lines down, so we were all off book by the second week of being in there.

And when he saw a scene got to the emotional level that he wanted it to be, he would go, "That's a print," in his little voice.

And we would all know that Sidney was saying to us in a very simple way, "There's a lot of emotional rollercoaster going here.

That's where I need this scene to get to in this particular place in the movie."

That is extraordinarily helpful.

It's also great to learn to trust other actors.

You get comfortable with one another.

I don't think I've rehearsed as many days in the last 80 movies since, as I did the 30, 35 days I rehearsed on Prince.

- And in that period, he often said that you worked very intensively.

Can you talk a little bit about that process?

- Well, he was an actor, and sometimes working with him was almost like working with another actor.

There was a scene where I was really a little bit lost 'cause I had not seen this character.

And I had to do this angry Italian guy yelling at at somebody.

And I was imitating him in sort of a wise guy way.

And Sidney said, "No, no.

It's gotta be really heightened, you know?"

And he said, "The guy's gotta be like, flipped out, "you son of a [Censored]!"

You gotta be doing that.

And I said, "Oh, I can go there.

Okay."

So what was great with Sidney was if he demonstrated, it wasn't a bad director demonstrating bad acting, which is just, it's death to an actor to have somebody give you a line reading.

- How does this fit into the kind of pantheon of films that you've made?

How does it, does it stand out in a very special way?

Oh yeah, it's... - I would say, I'd put them equal.

The number ones are, "Hair," and, "Prince of the City."

And then they start to in descending order.

The thing I love about Sidney's directing is, his films are completely different.

You'd never think the guy who directed, "Prince of the City," could direct, "Murder on the Orient Express."

You know, they're just...

So he's one of those few directors that would completely just immerse himself in the milieu and in the environment of that particular movie and that kind of acting.

Completely different kind of acting in that film too, you know?

- Well, he loved work.

He loved making movies.

And if he found a good script, he was gonna make it.

It didn't have to - Yeah.

satisfy an agenda.

- Yeah, and he wasn't afraid of being theatrical.

What the hell's wrong with being theatrical?

No wonder he got thrown outta the Actor's Studio.

You know, sometimes you gotta be bigger than life.

And a lot of his films, you know...

But he was also not afraid to fail.

He went out and made, "The Wiz."

He'd never done a musical so he, you know, he... That's one of the things I really admire about him as an artist.

He said, "Oh hell, I'll just go do it.

What?

You know...

They're not gonna shoot me.

I'll go make this movie and see how it goes."

But look what's risen to the top.

- The more we think about him, the more we realize how extraordinary he was.

- I think though, I think we all know we were working with one of the greats and he made it comfortable for us.

Come on a set, give you a kiss, "Let's go to work."

You know, he was just always a ball of enthusiasm.

And if I may say on camera, he was a 'no [Censored]' guy, which I loved about him.

He was great, great.

Sidney wasn't afraid to give you his love.

He held nothing back.

You felt that he cared about you and your talent.

He made you feel safe.

I always felt very safe acting in front of Sydney.

And he knew how to say, if something wasn't working, "That's great.

Let's, why don't we try this?"

He was just really, I'd have to say, the greatest American film director I worked with, in terms of all encompassing, all aspects of film.

And I miss him, I miss him.

Like to say that I miss working with him and, but I got to.
