Steve Papazian, who has been with the company for 47 years and through the various incarnations of management at the studio — from Terry Semel and Bob Daly, through Alan Horn and Jeff Robinov to the current regime of Kevin Tsujihara — is leaving his President of Worldwide Production post and is now Worldwide Production Executive. He will serve as a consultant on physical production for the next two years.

The trusted executive, who started in the mailroom at the company, is a seasoned physical production executive who has worked on some of the studios biggest films during his long stint.

Papazian most recently oversaw physical production on Batman v Superman: Dawn of Justice, Suicide Squad and Fantastic Beasts and Where to Find Them.

As President, Worldwide Physical Production for Warner Bros. Pictures, Papazian was responsible for overseeing all aspects of physical production for films produced by the studio and New Line Cinema domestically and in locations around the world.

“I’ve worked with Steve on a number of films over the years and his encyclopedic knowledge of global locations and infrastructures has been invaluable,” said Clint Eastwood when the studio made the announcement. “Steve and his team are an incredible resource and have helped get our productions the access, locales and landmarks that become a key part of a well-told story.” The filmmaker said he was happy to know that “his expertise will still be available to us.”

Added Nolan in a statement:, “I’ve had the pleasure of working with Steve on some extremely challenging and complex projects over the last 16 years. His knowledge of film craft and production techniques are second to none, and I’m looking forward to using him as a resource to draw on and a guide to listen to for as long as he’ll let me.”

Other films produced during Papazian’s tenure include the global hits Interstellar, San Andreas, Godzilla, Man of Steel, The Great Gatsby, and the Academy Award Best Picture winners The Departed and Argo.

“Warner Bros. truly is home to me. I’ve been very fortunate to spend all but two years of my professional life here and could not be prouder of the company or my colleagues,” said Papazian in a statement. “While almost every aspect of the business has changed over the years, what hasn’t changed is that this is a great company that I love to come to work at every day.”
