Leonardo DiCaprio

Leonard DiCaprio, 49, played fictional Hollywood star Rick Dalton, the star of Western show 'Bounty Law' who is struggling to find his place in a changing Hollywood, in 'Once Upon a Time... in Hollywood'.

DiCaprio was impressed by Tarantino's meticulous approach to movie making.

He said: “Not only is he forensic in showing an audience a specific time period in a certain culture, mixed with fairy tale, mixed with tableau of memory, but all these things fit in a very unique way, the way that you don’t see in modern filmmaking. That’s why it’s so incredibly exciting to work on his movies because there’s this unexpected nature. Every day you’re on set, you don’t know what’s going to happen and everyone feels incredibly energized and excited to be there because there’s the great unknown.”
