This has more twists than...well, a Saw movie.

Okay, follow along with me now.

1. Writer/director James Wan and writer/actor Leigh Whannell create Saw, released in 2004.

2. Saw makes millions of dollars, becomes the most profitable horror franchise of all time.

3. In 2009, the sixth film in the series gets the best reviews since the original.

4. But gets beaten up and has its lunch money stolen by an upstart called Paranormal Activity.

5. Saw VI director Kevin Greutert is hired to direct Paranormal Activity 2.

6. But the distributors and producers of the Saw films activate a clause in his contact, obligating him to direct VII instead.

7. The team that made Paranormal Activity signs a deal "to finance and produce low-budget genre pics."

8. Their first to be written and directed by...Leigh Whannell and James Wan.
