Following Oppenheimer's global theatrical release, one moviegoer spotted a minor historical error.
Andrew Craig, director of Election Policy at the Joseph Rainey Center and adjunct scholar at the Cato Institute, pointed out that 50-star flags are used in a scene that takes place in 1945. The scene in particular sees Oppenheimer (Cillian Murphy) address the residents of Los Alamos, who are celebrating after a 'successful' detonation of the Trinity bomb. The correct flag flies behind Oppenheimer in another celebratory scene just before this.
