At the Disneyland premiere for his upcoming film Tomorrowland, George Clooney talked about the way his wife, Amal, has affected his perspective on things.
"All I know is that it sort of changed everything in terms of what I thought my future – my personal future – was going to be," he told PEOPLE when asked how connecting with Amal, 37, a distinguished human rights lawyer, changed his vision for the future.
"But I've always been an optimist about the world," the actor, 54, continued.
"I wasn’t always completely optimistic about how it was going to work out personally for me. But now I am."

The couple, who attended the film's Saturday premiere at the Anaheim, California, theme park – where a special Casamigos Tomorrowland Orbiter cocktail was served – has had an eventful week.
On Wednesday, they celebrated his birthday with an intimate gathering at his L.A. home.
The actor's production partner Grant Heslov, Cindy Crawford, and her husband Rande Gerber, were in attendance at the cocktail party, along with about 50 other guests.
Asked by reporters on Saturday about how he rang in his first birthday as a married man, he responded: "By drinking, unfortunately."
