Newton-John: 'I was unsure about Grease'

Olivia Newton-John has revealed that she was not sure about taking the iconic part of Sandy in hit 1978 musical Grease.

The actress told Metro that she still does not mind being best remembered for the role.

She said: "Maybe in 20 years it'll be weird. That movie gave so many people pleasure, I can only be happy about it. And to think I was actually unsure about taking the role.

"I'd just made a movie called Tomorrow and it was a disaster. My musical career was just about to take off and I didn't want to jeopardise it."

She added: "I was 29 and worried about looking 18 for the film. Then I didn't think I could do an American accent, so they wrote me in as an Aussie."

Newton-John also joked that she "wouldn't want to try" to fit into the leather trousers she wore for the film's final scenes.
