Director M. Night Shyamalan has teased his next movie. Writing on Twitter, Shyamalan said he already has an outline for his next film, suggesting that it could be a sequel to the thriller Split. That movie starrs James MacAvoy as a man with 23 different personalities--and it had a big twist ending.

　　The tweet (via EW) is immediately below, while spoilers for Split follow further down the page.

　　I have an 11 page outline for my next film in my bag. I can't tell you what it is, but If you've seen #Split...

　　The ending of Split revealed that McAvoy's character, Kevin, had a 24th personality, The Beast, a bloodthirsty and superhuman force. Not only that, but the final sequence confirmed that Split and another Shyamalan movie, Unbreakable, exist in the same universe.

　　In an interview, Shyamalan said he hopes to make a movie that combines Split and Unbreakable, so that could be the sequel he teased on Twitter.

　　Split was the No. 1 movie at the US box office this past weekend, extending its streak to three straight weeks. Made on a reported budget of $9 million, the movie has now made more than $142.7 million worldwide, according to Box Office Mojo.
