'Scream 4' Secrets: The Extraordinary Lengths The Cast Went Through To Prevent Spoilers

Every movie depends on secrecy to a degree, but the "Scream" franchise hinges upon it entirely. If you go into your first screening knowing who the killer is, there's no question that you're missing out on some of the wonder that Wes Craven and his team have in store for you.

"Scream 4" hits theaters tonight at midnight, and thankfully, the biggest secrets of the film remain largely unspoiled online and elsewhere. It's actually not surprising that Dimension has been able to keep a lid on things for so long — because not even the cast of the movie themselves were allowed to read a full "Scream 4" script in order to prevent any and all possible leaks.

After the jump, hear the enormous lengths that the "Scream" team went through to keep their secrets from the actors themselves.

Hayden Panettiere

"[I got] the middle bit, the middle section. I was in Germany and [the filmmakers] had somebody fly to Germany, meet me at home to watch me read the middle part of the script, so there was no beginning, no end, subject to change. There's just something very funny about somebody sitting there watching you read it to make sure you don't sneak pictures or go sending it anywhere. You feel like your life may be in jeopardy if, God forbid, anything got out."

Emma Roberts

"When I first read the script, I had to read it at [director] Wes Craven's house. So I couldn't even have it sent to my house. When we got our scripts on set, they all had our names on them and I remember I was getting out of my car to go to work one day and I dropped my script and, literally, the pages were everywhere and I was in this parking lot chasing after all of my pages and, of course, the last few pages were floating away from me … I grabbed them and brought them to my trailer, [thinking], 'OK, I don't know what to do with all this paper, I'm so nervous to be carrying this around.'"

David Arquette

"I didn't receive a full script, no. It's always been a whirlwind when these films get going. You never really know what's happening, what's going to happen, and also how it works in the films ... when I go see these movies, there's a lot of, 'Oh, they kept that? Wow, that worked. Oooh, scary.'"
