United Kingdom, Dec. 30 -- George Clooney has "rediscovered" his love of acting.

The 64-year-old actor feels he's recently emerged from an unsatisfying spell in his career, having taken on some relatively easy film roles.

He told Variety: "I got my groove back as an actor.

"I rediscovered why I love this profession. It's not that I wasn't challenging myself on my last few films, but I knew how to play those parts."

By contrast, George relished the challenge of playing a movie star past his matinee idol prime in Jay Kelly.

He said: "With this one, I felt like I did when I started acting and was trying to figure it out. You're thinking, 'Am I a fraud? Am I going to be found out?' It's a really good place to be, to feel off your game."...
