Trailer: Grease

Good girl Sandy and greaser Danny fell in love over the summer. When they unexpectedly discover they're now in the same high school, will they be able to rekindle their romance?

Olivia Newton-John has hinted she and John Travolta will reprise their iconic roles as Sandy and Danny from the hit musical Grease in order to mark the film's 40th anniversary. 

Grease first hit cinemas in 1978 and snapped up close to $US400 million at the box office. 

The film catapulted Newton-John into stardom. The British-born Australian would later star in numerous films and snap up a total of four Grammy awards.

While Newton-John told the UK Mirror there is "nothing to announce yet", she did confirm she and Travolta had been talking about how they could honour Grease's 40th anniversary. 

"We are thinking up ways," she said. "I can't believe [it]. Time goes so fast. It is so exciting." 

The four-time Grammy award winner, who grew up in Melbourne before finding fame overseas, hinted that the Grease tribute could be one of her last public performances.

The 68-year-old said while she loves singing, travelling has started to get "tiring". Over the years, she has also increasingly channeled her time and energy into her charity work - including raising money for the Olivia Newton-John Cancer Research Institute in Melbourne.

"As time goes on I think of doing less and having more time off," she said. "Every year for the last 20 years, I thought I was retiring and then somebody would say, 'How about this?'"

Grease's 40th anniversary is due to be celebrated in June 2018.
