"Barbie" and "Oppenheimer" will both be released in theaters on July 21. Warner expects the film based on the Mattel doll to take up to $80 million in its first three days. That's about double the projected box office take for Christopher Nolan's epic over the same period. For about a year, a box office battle has been brewing between "Barbie" and Oppenheimer" — the two much-anticipated films from Oscar-nominated directors that are set to be released on exactly the same day. That's before the release of more blockbusters, including "Mission: Impossible – Dead Reckoning Part One" and, of course, "Barbie" and "Oppenheimer."
