'Oppenheimer' -

A glaring error was caught by fans in Christopher Nolan's 'Oppenheimer'; the critically acclaimed film about the scientist who helped develop the atomic bomb. In one scene, Oppenheimer stands in front of a crowd of people in Los Alamos in 1945, and people in the crowd are waving US flags which have 50 stars. To most people this wouldn't be cause for concern, but history buffs know that the 50-star flag didn't exist until 1959 when then-president Eisenhower officially established it with Executive Order 10834.

'Emily in Paris' -

An incredibly glaring error made it into the final cut of an episode of 'Emily in Paris.' In episode three of the third season, Emily (played by Lily Collins) walks around a hotel room in Paris and fans noticed that the one and only Eiffel Tower can be seen out of two different windows! The show already includes the iconic landmark in as many scenes as possible, and TikTok users were quick to make fun of the mistake. "Fun fact: the Eiffel Tower exists outside of space-time and can appear within eyesight of anyone in Paris no matter which direction they're facing," one user joked.

'Bridgerton' -

Shonda Rhimes' hit Netflix series 'Bridgerton' has attracted a huge audience, which is great but also means that ever more watchful eyes are trained on production for mistakes. But who would have thought they'd find some in the premiere episode? That's right, eagle-eyed viewers noticed that the Regency-era drama had a splash of modernity in it. The episode begins with a scene showing the town square, spotted with horse-drawn buggies and elaborate costumes, but one shot reveals a yellow traffic line atop the cobblestone street, which didn't originate until the 1940s, according to CNN.

'The Tudors' - 'The Tudors' took a stylized approach to the life of King Henry VIII, portrayed by the talented Jonathan Rhys Meyers. The actor's appearance hardly matches the historical records of Henry VIII. The show also meddled around with the time Henry married Anne Boleyn.
