In a followup to the 2013 hit horror film "The Conjuring," Ed and Lorraine Warren (Patrick Wilson and Vera Farmiga) will be heading to England to help a family with two sisters that are possessed by unknown entities, as reported by Dread Central.

The film will be titled "The Conjuring 2: The Enfield Poltergeist," and it is based on the real-life investigative case of the Ed and Lorraine Warren, who were first brought to mainstream notoriety following their investigation of the Amityville house haunting, which ended up in popular fiction as a book and a movie in the late '70s.

The sequel raises an interesting question though, as reported by Movie Pilot: "Are they filming the real life cases of the Warrens in chronological order?"

The actual case of the Perron home, which was the subject of the first "Conjuring" movie, occurred in 1971. At the end of the movie, when all was well and they were wrapping up, just before the credits Lorraine said to Ed that the Vatican had a case in Long Island they want them to look into.

See that video here.

The Long Island case was the "Amityville" haunting. The movie kind of causes a chronological divide here since the Warrens did not investigate the Amityville case until 1976. That made audiences wonder if that was just Lorraine seeing five years into the future or if the time had already passed in that ending scene.

But the next question is, Why did they skip over Amityville and go to Enfield for the sequel?

If the franchise were to place these events in chronological order, then Enfield would have been reserved for part 3 because, in real life, that happened in 1977.

It also doesn't make sense that they would end the first movie with such an illustrious tease for the sequel going to Amityville, given the gaping plot hole of logic that the case won't occur for another five years, and take the sequel to Enfield, which took place one year after Amityville.

A theory in the Movie Pilot article suggests that they did do Amityville and those scenes would play out in flashbacks during the "Enfield" sequel. Keep in mind, a prequel is not highly likely given that they already did one with "Annabelle" last summer.
