The Clint Eastwood Archive: American Sniper premiere held at Lincoln Centre on Monday, December 15th in New York City

When asked what he learned about that part of film-making from his experience on American Sniper, Cooper said, "a tremendous amount."

"Everything that goes into making a movie from buying the rights to a book to standing right here talking to you," he added on the red carpet, saying he really learned about how collaborative the process of making a movie is. "You want to surround yourself with people who have the same kind of work ethic that you do."

Warner Bros. execs Sue Kroll, Greg Silverman, Dan Fellman and Kevin Tsujihara were also on hand for the film's New York premiere along with Cooper's Elephant Man co-star Alessandro Nivola, Inside the Actors Studio host James Lipton, Benjamin McKenzie, Tia Mowry, Montel Williams, Bob Woodruff, actress and Fox News contributor Stacey Dash, Stephen Baldwin and others.
