According to The Hollywood Reporter, Dunst, who took home the 'Best Actress' prize for the film, expressed her gratitude to the festival for not banning the movie following von Trier's remarks about sympathising with Hitler.
"This is an honour that's once in a lifetime. Thank you to the Cannes Film Festival for allowing the film to still be in competition," Dunst said.
The actress went on to thank her director as well: "I want to thank Lars for giving me the opportunity to be so brave in this film. It's such a special night for me."
Von Trier was banned from Cannes after making the controversial comments. The director claimed that he was proud of the ban, but later apologised.
