The 41-year-old Revenant star skipped the carpet, but showed up to support movie producer Harvey Weinstein, who was being honored that night.
Leo recently opened up about the massive success of Titanic.
“Titanic was very much an experiment for Kate Winslet and I,” Leo told Deadline. “We’d done all of these independent movies. I loved her as an actress and she said, ‘Let’s do this together, we can do this.’ We did it, and it became something that we could’ve never foreseen.”
He added, “My whole life became about things that weren’t about acting.”
