Los Angeles: "Tomorrowland" star George Clooney has revealed his wife, Amal, has made him optimistic towards life.

Clooney, 54, said the 37-year-old distinguished human rights lawyer has changed his vision for the future, reported People magazine.

"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.

The couple attended Tomorrowland's Saturday premiere at the Anaheim, California.

Asked by reporters about how he rang in his first birthday as a married man, he responded, "By drinking, unfortunately."
