Actor George Clooney "wanted to strangle" co-star Britt Robertson while filming `Tomorrowland: A World Beyond` because he believed "she's so talented".

The 54-year-old worked with the 25-year-old star in his new film and said he felt like more of a child than her because "she's so talented", reports femalefirst.co.uk.

Speaking at the film's European premiere at the Odeon cinema here, he told BANG Showbiz: "As you can imagine, I didn't care for the children ... Britt is an old pro, she's been doing this for a long time and she's incredibly talented and she's going to have a long and bright future... I just wanted to strangle her, she's so talented.

"They were all great. I was the kid and they were the adults."
