Somebody is writing a prequel to Se7en.
The movie is called Virtue, and it will be marketed as a regular film. Only at the end will it be revealed that the film is a prequel to Se7en.
Why would you hide that it's a prequel to Se7en when the target audience is ostensibly fans of Se7en? Learning that it's a prequel to Se7en certainly piqued my interest.
Also: After both Dumb and Dumberer and Son of the Mask bombed, you'd think New Line would stop considering belated sequels.
