You'd have to write that into the story though. Like a frame where the police find the dead ninja and one cop asks "Why do his eyes look that way?" and then another replies with "That's what your eyes look like after you've gazed into Hell. Haven't you seen The Beyond?". The first cop then says "No, I haven't.". You could even make him look like me, since I too haven't seen The Beyond..
Except all movies/video games/bands and such in the 198X-verse have to have a parody name that is usually another way to say the same thing (e.g.
New Kids on the Block becomes
Fresh Teens on the Street), or the parody name references the content of the original (e.g.
Caddyshack becomes
Gopher Golf). So
The Beyond would become something like
The Afterlife (if I were feeling lazy) or perhaps
Hellgate Hotel.
That's true, but isn't that mostly to save money on the special effects budget?
I believe the tradition began in books and folktales well before film came along, so I don't think that's the only reason. Besides, it allows you to have the big dramatic reveal where the girl discovers that the evil werewolf that she just killed was actually her boyfriend/teacher/grandpa/mail man. Or, if the story wants to be even more shocking, the beast will turn out to be a woman. Oooooo...
