The Passion of the Christ was based on two (or five, depending on how you look at it) sources: the four Passion accounts of the Evangelists Matthew, Mark, Luke, and John; and Blessed Anne Catherine Emmerich’s Dolourous Passion vision. I assume Gibson is going to continue the rule of “scripture and accepted visions” for his movies, but his new movie is going to depict the harrowing of Hell, which isn’t something deeply covered in The Bible. Looking into Emmerich, she only had visions on the Passion and the life of the Virgin, she didn’t have any visions of the harrowing of Hell. Does anyone know what this new movie is based on? Has Gibson said anything on this? Alternatively, are there any famous visions of the harrowing that this movie will take reference from?
