10 Great Horror Movies Made In Really Weird Ways

10. It Was Constantly Rewritten During Shooting (Due To Leaks) - Scream 2

Looking back, it's basically a miracle that Scream 2 turned out as well as it did - an all-timer horror sequel that released less than a year after Wes Craven's original took the world by storm.

But given the popularity of the first Scream and the Internet becoming more widely adopted in the late 1990s, Scream 2 also had to deal with constant set leaks.

As shooting started, Kevin Williamson's script was leaked online in full, forcing him to make a risky pivot, substantially rewriting major portions of the story while filming was going on.

Because the killers and every significant plot beat was out in the open online, Williamson changed the identities of the killers and the fates of several characters, while near-totally reimagining the finale.

Due to the frantic schedule, Williamson wasn't always able to keep up with the speed of production, and so Craven had to write and effectively workshop some scenes on the day they were filmed.

Yet watching the final film, you'd basically never guess it was the result of an enormously strained, time-pressured creative process.
