Matthew McConaughey: Working on animated film Sing really not hard work

Updated: 

Matthew McConaughey has said he did not have to work hard on his new animation Sing, as he joined fellow Oscar winner Reese Witherspoon and Scarlett Johansson at the film's premiere in Toronto.

Matthew provides the voice of Buster Moon, a koala bear who owns a struggling theatre and stages a singing contest for an array of animals in a bid to raise money.

The actor, who won an Academy Award for his role in Dallas Buyers Club, said working on the animated comedy made him feel like a child again.

"It's really not hard work, to be honest," he said. "I found the first time I went in the booth, I had an idea for the voice, the director liked where I was going with it, we were off and from there it's just playing.

"I got to use my imagination a lot quicker in this than probably anything else I've done. I feel like an eight-year-old again which is good."

Reece, who won a Best Actress Oscar for Walk The Line, voices Rosita, a domestic pig who gave up her teenage music dreams to become a devoted wife and mother.

Speaking at the Toronto International Film Festival (TIFF), she said: "I play a mum who has 25 kids and I think a lot of parents can relate to the idea that you give up a lot of your dreams for your children.

"I've only ever been to TIFF with serious dramas so this is really fun."

Scarlett, who voices Ash, a singing porcupine, said she enjoyed answering questions about a family film in contrast to her recent role as a computer operating system in the 2013 film Her.

"It's great to be at any festival with a film you believe in," she said. "Of course it's easy to answer questions about being a punk rock porcupine than, 'what's it like turning into a computer?'"

Sing is due to be released in UK cinemas in January.
