There was no shortage of teaser trailers during last night’s Super Bowl LIII, and Avengers: Endgame was one of the most highly anticipated. The teaser was the perfect length: short enough to leave fans wanting more, but just long enough to generate some juicy conspiracy theories.

One of the most talked-about aspects of the teaser was the scene in which Scarlett Johansson’s Natasha Romanoff/Black Widow, Chris Evans’s Steve Rogers/Captain America, Mark Ruffalo’s Bruce Banner/The Hulk, and Don Cheadle’s James Rhodes/War Machine stand awestruck outside of Avengers HQ and walk toward something, with their heads tilted sharply up toward the sky the entire time. The unique shot has sparked a debate about what, exactly, they are looking at. But according to ComicBook.com, some eagle-eyed viewers noticed something even more peculiar: It appears one of the on-the-ground character might’ve been edited out of the shot.

One theory as to who that missing Avenger might be is Tony Stark/Iron Man, who earlier in the trailer is seen stranded in outer space and trying to make his way back to Earth. If he's not the erased character on the ground, he could also be who the heroes are looking up to in the sky. However, even more fans are convinced that the airborne interest is in Brie Larson’s Captain Marvel, as producers would likely want to keep her appearance in Avengers: Endgame under wraps until her solo movie drops in March.

But those aren't the only guesses: Some fans think the character edited out on the ground could be Jeremy Renner's Hawkeye/Ronin. And as for who they’re looking up at? Some say it could be Paul Rudd's Ant-Man—or even Josh Brolin's villainous Thanos. Clearly, we have as many questions as we do unsubstantiated answers.

The scene has created enough speculation to make it a hot topic until the final installment of the Avengers series makes its way to theaters on April 26, 2019.
