The film has grossed approximately $80 million globally, with $50 million coming from the U.S. market alone, showcasing strong international performance with upcoming releases in major markets like France and Germany. It ranked in the top two in 32 markets and was number one in 12, benefiting from positive audience reception reflected in a 94% Rotten Tomatoes score.
