\n Grease musical is one we want \n Grease star dies, aged 60 \n It's the film that catapulted Olivia Newton-John and John Travolta to fame and formed a lifelong friendship between the pair. But what if casting for Grease had gone a little differently? According to a report by Vanity Fair, the roles of Sandy and Danny nearly went to Carrie Fisher and Henry Winkler. The article claims bosses at Paramount wanted Danny to be a gas station attendant played by Henry Winkler, the star of Happy Days. Winkler, already well known for his character Fonzie, turned down the role, reportedly because he didn't want to be typecast. Travolta, 22, eventually signed on, but only after he could make disco hit Saturday Night Fever. Newton-John was also nearly overlooked in favour of Fisher, who was at the time shooting George Lucas' first Star Wars film. Grease director Randal Kleiser approached his old college friend Lucas to see whether Fisher would be appropriate. But he couldn't judge Fisher's singing or dancing abilities and decided to keep looking. It wasn't until Grease producer Allan Carr was sitting opposite young Australian actress Olivia Newton-John at a dinner party that they found their Sandy. However, Newton-John, an aspiring singer, had just starred in science-fiction bomb Toomorrow, and didn't want to compromise her music career. "I was very anxious about making another film, because my music career was going well," Newton-John told Vanity Fair. "I did not want to mess it up by doing another movie that wasn't good." She also worried that at 29 she would be too old to star opposite Travolta and was concerned that she couldn't do a convincing American accent. Carr and Kleiser fixed this by making Sandy an Australian and, in the end, Newton-John and Travolta had great chemistry. "She had a brilliant voice, and I didn't think there could be any more correct person for Sandy in the universe," Travolta said. "I never let up on it. I insisted that she be met and that we cast her."
