If you like your horror movies, get ready to scare yourself stupid at this trailer for Sorority Row!

We like a sorority movie at Sugarscape - Legally Blonde, The House Bunny, er, that's about it.

But new movie Sorority Row isn't the usual blonde, fluffy piece of pink sisterhood. Oh nooo.

When a group of Sorority Girls play a prank that goes horribly wrong, the film turns slasher.

It stars a lot of up and coming US girls, including Rumer Willis, who obvs can't get enough of the Alpha Beta Gamma business after appearing in The House Bunny...

She plays geeky girl Dale. Loving those Thelma glasses Rumer!

Watch the trailer right here...but be warned!

It's scare-tastic!

What do you think of Sorority Row?

Will you be watching it when it comes out in October?
