Luhrmann said that throughout his career, with films such as Strictly Ballroom, Romeo + Juliet and Moulin Rouge, he "never got high critic scores".
"I knew it would come. What about Fitzgerald? What about him writing that book? What about [being called] 'a clown'? I just care that people are going out and seeing it."
One person who has approved of the adaptation is Eleanor Lanahan, Scott and Zelda Fitzgerald's granddaughter, born four years after the author's death. She approached the director following the premier, and told him: "I think Scott would be proud of this film, because people have said for many years you cannot take his first person narrative and make it into a film. I think you've done that."
Luhrmann said: "For me that was about as good as it could possibly get. If we've done anything, that's made it worthwhile."
Critics who have praised the adaptation have said it was "unmistakably F. Scott Fitzgerald's The Great Gatsby" and it was "the best attempt to capture the essence of the novel".
DiCaprio, who worked with Luhrmann on Romeo and Juliet, said Luhrmann "inspires you in the workplace, not only to do your best, but dream big".
