Just watched the #Rocketman premiere at #Cannes2019. An amazing #EltonJohn musical & biopic with sprikles of surrealism throughout. Great performances and SO well shot ❤️???? — Lucas Rizzotto✈️ Cannes ???????? (@_LucasRizzotto) May 16, 2019

I’m not an objective viewer but I really enjoyed #Rocketman. It’s a lovely tribute to Elton’s partnership with Bernie & the fantastical tone suits his life perfectly. Oscar chances hinge on reviews & biz, but as a true musical it’s a great bet for picture & actor at the Globes. pic.twitter.com/e1AlNsqfvf — Dave Karger (@davekarger) May 16, 2019
