In a mysterious prank, the website AvengersEndgame.com redirects users to a promotional website for Fox's soon to release Once Upon a Deadpool. After months of - admittedly self-created - anticipation from fans about when Marvel Studios and Disney would finally drop the first trailer for Avengers 4, the big event finally occurred Friday morning, along with confirmation of the film's official title. Needless to say, Marvel fans have been spending most of the day since analyzing every frame of the trailer, looking for clues about what's to come.

As expected, none of the characters dusted by Thanos appeared in the trailer, although provocative questions like "how will a stranded Iron Man get back to Earth" or "how did Ant-Man escape from the quantum realm" were raised before the end of the first look at Avengers: Endgame. Tomorrow brings with it the arrival of the trailer for Spider-Man: Far from Home, despite the fact that fans don't even know how Peter Parker gets resurrected yet. That said, those are both 2019 films. Before 2018 ends, Deadpool is set to return to theaters with Once Upon a Deadpool, a PG-13 re-cut of Deadpool 2 framed by scenes featuring the Merc with a Mouth and a kidnapped Fred Savage.

One wouldn't expect Avengers: Endgame and Once Upon a Deadpool to have anything to do with each other, as one is part of the MCU and the other is part of Fox's X-Men universe. Yet, in one odd way, the two films have been connected. As reported on by THR, what seems like the most obvious URL to visit for information on Avengers 4 or to re-watch its trailer, AvengersEndgame.com, instead redirects to a promotional page for Once Upon a Deadpool. Making things weird is that it seems unclear why exactly this redirect was created.

Deadpool and The Avengers

Now, the first logical guess is that this URL redirect is simply a publicity stunt. After all, Fox's sale of its movie and TV studios - plus all the franchises those studios contain the rights to - to Disney is nearing completion, so it wouldn't be shocking to learn the two studios collaborated on an amusing bit of cross-promotion. This also seems like the exact type of thing Deadpool star Ryan Reynolds would do. However, it may not be that cut and dry.

The Twitter account @AGuyInChair claims to own the AvengersEndgame.com URL, and that he made the decision to redirect the website to Deadpool-related content. THR says they exchanged DMs with that account, and the person who responded says that they aren't Reynolds, and bought the website URL back in April, when Avengers: Infinity War released. The person also claims to have had advance knowledge of what Avengers 4's title would be. Making that explanation a bit difficult to believe is that the account in question didn't exist until Friday afternoon. For now, fans can only wonder how this intriguingly strange situation will ultimately be resolved.
