Last week, directors Anthony and Joe Russo shared an "Avengers: Infinity War" location scouting photo on Twitter. It's nothing out of the ordinary since the Russo brothers do this often. But for some mysterious reason, they decided to remove the image. This move certainly caused a stir, and fans began to speculate that maybe the photo gave out something the directors don't want to reveal just yet. The photo might be deleted but a number of people managed to copy it before it was taken down.

Redditors have pointed out that the photo was taken at Durham Cathedral in the United Kingdom. Fans have come up with a number of theories on what the location would stand in for, but many actually believe that this could be Doctor Doom in Latveria.

Before anyone gets too excited, it should be noted that 20th Century Fox currently owns the film rights to the character. This theory may seem a bit far-fetched, but it is still a possibility. After all, Marvel and Fox did negotiate a character trade to help each other out.

Marvel fans have been dying to see the iconic villain battle the Avengers. If Marvel can somehow get back the rights to Doom, Kang, Annihilus and Galactus, the Marvel Cinematic Universe will have a great lineup of villains for Phase 4.

Some fans speculate that the location may stand in for Asgard instead since it looks like the place Thor (Chris Hemsworth) was in when he was having his visions. Others say it may be Mistress Death's lair. Well, if "Avengers: Infinity War" sticks to the source material, this character should make an appearance.

Right now, readers are advised to take everything with a grain of salt because these are just theories and speculations that people have come up with.

"Avengers: Infinity War" is scheduled to premiere on May 4, 2018.
