It's just hours after Marvel Studios revealed the first trailer, and title, for Avengers: Endgame , but the URL for the newly titled Avengers 4 does not go to a site for that film.

It is unclear who is behind the URL redirect, but shortly after 9 a.m. PT (three hours after the trailer dropped), a Twitter account with the handle @AGuyintChair tweeted it owned the domain and was asking for a pair of tickets to the Endgame premiere in exchange for it. According to records, the domain was registered on April 27, which was opening day of Avengers: Infinity War.

In a direct message exchange, the owner of the Twitter account told The Hollywood Reporter they knew back in April that Endgame was the name of the next Avengers film. They declined to divulge their identity and said Disney had not been in touch about obtaining the domain. While this might seem like a marketing prank Deadpool star Ryan Reynolds might pull, the owner of the Twitter account said they are not him.

Disney is in the process of acquiring 21st Century Fox, which has the rights to Deadpool and other X-Men characters, as well as the Fantastic Four. It's unclear how these Marvel assets will be integrated into the Disney-owned Marvel Cinematic Universe, but Disney CEO Bob Iger has said that Marvel Studios head Kevin Feige will have purview over those characters. He has also indicated that, despite Disney's family-friendly brand, he could see Deadpool being allowed to remain R-rated when he moves to Disney.
