Moviegoers have spotted a blooper in ‘Oppenheimer’

Some moviegoers have noticed a mistake in a scene in Christopher Nolan’s latest film, “Oppenheimer."

Christopher Nolan’s latest film, “Oppenheimer,” has become one half of the box office and pop culture phenomenon “Barbenheimer,” sweeping up glowing reviews along the way.

But eagle-eyed fans have spotted a mistake in a scene set in 1945, as Cillian Murphy’s J. Robert Oppenheimer stands among a crowd waving American flags – bearing the wrong number of stars.

“It was good and all, but I’ll be that guy and complain they used 50-star flags in a scene set in 1945,” Twitter user Andy Craig wrote on Friday.

In 1945, the American flag featured 48 stars, as Alaska and Hawaii hadn’t yet become U.S. states.

It wasn’t until July 4, 1960 that a 50-star flag was first flown in the U.S..

But in another scene set in the same year, the correct American flag flies behind Oppenheimer.

One Twitter user had a theory: “I can argue that this is done intentionally as the colored scenes were from Oppenheimer’s perspective, while the black and white scenes were from another. This would be a memory of Oppenheimer from his present day memory which does have 50 states on the flag.”
