Roger [Corman] didn't actually hire me, though. I was hired by AIP [American International Pictures], the studio that made the picture, which was Sam Arkoff and Jim Nicholson. It was a great learning experience for me, because not only did I work on the script, but they hired me back to go on location when they were making the movie, to write new scenes and so forth.

It was also a new role for me as a writer, because I wanted to just be there to serve Sam. I recognized that this picture would be "a Sam Fuller movie," and I was just trying, in whatever way I could, to help him get what he wanted.

I look for characters that interest me, and a story that keeps me involved and makes me want to know what happens next.

Of course, Sam [Fuller] was like, "No problem," because he treated it like a newspaper deadline. We worked long hours, often very late into the night, in his garage, which had been converted into an office. It was freezing cold outside and there was no heat in the garage, so he had a little space heater over by his side and I had a blanket that he graciously gave me to drape around my shoulders like a Navajo Indian. And he gave me cigars, too, of course.

I had always wanted to tell a story that was set in Los Angeles in the '50s, because that's where I grew up, and it was the city of my childhood memories.

When I first went to Pittsburgh, I had never been there before, and we hadn't even decided to shoot there yet. I just went to see the location of Michael Chabon's novel. Once there, I became aware that Pittsburgh is a "wonder boy," in the narrow sense of the term, just as the human characters are.

You can dress it up, but it comes down to the fact that a movie is only as good as its script.
