Some serious Broadway crossover!
Once Grease had crushed the box office, many believed that it was time to revive the original Broadway play. Stars like John Travolta, Barry Pearl, Jeff Conaway, and Jamie Donnelly all headed over to Broadway as a result.
‘Hopelessly Devoted to You’ came in post
When the principal filming of the film wrapped up, the producers decided that Olivia Newton-John needed her own big song. Thus the memorable, raw ‘Hopelessly Devoted to You’ song was written and filmed in pick up shots. Newton-John would even go on to land an Academy Award nomination for that very performance.
