Matt Damon reflected on fame at the Independent Film Project’s Gotham Awards on Monday while being honored for his career. The “Promised Land” star first attended the event 15 years ago with Ben Affleck and Gwyneth Paltrow right before “Good Will Hunting” was released and Calvin Klein sent him a free suit to wear to it. “That was the first time that ever happened,” Damon told the crowd at Cipriani Wall Street. “As I was putting it on 15 years ago I realized . . . If I added up what all the clothes in my life were worth they wouldn’t be as much as the suit I was putting on.” He added, “That was kind of the first moment my life got really surreal,” before going on to thank his wife and family. Also at the CK Euphoria-sponsored awards event were Emily Blunt, Jared Leto, and “Silver Linings Playbook” director David O. Russell, whom Damon told he wanted to work with so much he’d hunt him down — “You’re like a wolf, and I’m like Sarah Palin in a helicopter. It’s only a matter of time, mother [bleep].”
