Avengers Endgame Poster Contains Thor Error, Reflects Early MCU Looks A new Avengers: Endgame poster shows Thor with a surprising error: his hair is from an earlier MCU film, not his Endgame look, while reflections show early versions. A newly released poster for Avengers: Endgame features a surprising error: Thor appears with hair from an earlier Marvel Cinematic Universe film, not his appearance in Endgame. The poster, shared on the official Avengers social media accounts, shows Thor, Iron Man, and Captain America with reflections revealing their earliest MCU iterations. The film returns to theaters on Sept. 25. Poster Details and Character ReflectionsThe poster displays Thor, Iron Man, and Captain America standing over reflective water. Each character's reflection shows an early version of themselves in the MCU. Iron Man's reflection is his original suit. Captain America's reflection is Steve Rogers before the Super Soldier Serum. Thor's reflection is his heroic look from his first solo film.However, the main image of Thor on the poster shows him with long hair, which does not match his short-hair look in Endgame. This has led many to believe it is an error. In Endgame, Thor had let himself go and was deeply saddened by his experiences, so his appearance was different.Avengers Endgame Theatrical Re-ReleaseAvengers: Endgame is set to return to theaters on Sept. 25. Marvel has been tight-lipped about what will be added to the movie, but teasers and posters have been released. This re-release is not the next major Marvel release, but it is highly anticipated by fans.The poster is otherwise visually stunning and meaningful, as it highlights the journey of these characters from their origins to Endgame. The error with Thor's hair stands out, though, and once seen, it is hard to ignore. It is unclear if this was intentional or a mistake.Impact and Fan ReactionsFans have taken to social media to point out the discrepancy in Thor's appearance. Some believe it might be a hint at a twist in the movie, but most see it as an error. The poster is for Endgame and should represent the characters as they are in that film. This misstep is unfortunate, considering the poster is otherwise brilliant.Marvel has not commented on the poster or the error. The re-release will give fans another chance to see the film on the big screen. As for Thor's hair, it remains a topic of discussion among fans.Avengers: Endgame was originally released in April 2019 and became a massive box office success. The re-release may include new footage or surprises, but details are scarce. The poster error has only added to the buzz surrounding the event.
