Grease success down to its stars
John Travolta and Olivia Newton-John are the secret to Grease's success, director Randal Kleiser has said.
The US filmmaker, who made his directorial debut with the 1978 musical starring the duo as high school couple Danny and Sandy, is surprised that it has continued to be a huge phenomenon 32 years on.
"The concept was pretty astounding and I don't know why it worked, from grandmothers to children and through different cultures - I think John and Olivia held it together," he said.
"The chemistry of John and Olivia, the simple story, and the songs all gelled together into something that people like."
Randal expects Grease's success to continue throughout the next decade and beyond, with the re-release of a sing-a-long version of the movie in cinemas.
"Unless people change drastically in the next 20 years, I don't know why it wouldn't just continue on. It's nostalgic, and fun to see. This version is interactive and adds a fun party atmosphere," he said.
"In the past, people knew the words but weren't encouraged to sing along and join in. People get up there and dance during the songs. It's really exciting because audiences applaud after every song."
Randal, who was also at the helm of Blue Lagoon and Honey, I Blew Up The Kid, has seen the new version four times.
"I still sing along! The most exciting time was seeing it at the Hollywood Bowl with 16,000 people singing along, cheering and dancing in the aisles. Not many directors get to have an experience like that," he added.
