In a recent interview with Deadline, actor George Clooney claimed that Matthew Perry was not happy while filming for the ‘F.R.I.E.N.D.S.’ TV show due to his drug and alcohol addiction.

Ocean’s Eleven actor George Clooney revealed to Deadline that Perry always wanted to act in a sitcom, and his dreams became a reality when he was cast as Chandler Bing in ‘Friends’.

However, Matthew Perry battled with unhappiness due to drug and alcohol addiction. “He was a kid, and all he would say to us—I mean, Richard Kind and Grant Heslov—was, ‘I just want to get on a sitcom, man. I just want to get on a regular sitcom, and I would be the happiest man on earth,’” George Clooney disclosed.

“And he got on probably one of the best ever. He wasn’t happy. It didn’t bring him joy, happiness, or peace,” Clooney continued.

George Clooney was unaware of Matthew Perry’s addiction, even though they worked side by side. He had no idea “what was going through him.” George Clooney was completing ER at the time, and Perry was in ‘Friends’.

“We just knew that he wasn’t happy, and I had no idea he was doing what—12 Vicodin a day and all the stuff he talked about—all that heartbreaking stuff,” Clooney told, referring to the shocking revelations Perry made in his memoir, Friends, Lovers, and the Big Terrible Thing.

Looking back at the state of his beloved friend Matthew Perry, George Clooney added, “And it also just tells you that success and money and all those things don’t just automatically bring you happiness. You have to be happy with yourself and your life.” (Read More: Matthew Perry Became ‘Angry And Mean’ Due To Testosterone Shots: Report)
