The carnage continues! MTV’s successful Super Psycho franchise is now a trilogy with the third installment of the made-for-TV movie, My Super Psycho Sweet 16 Part 3, premiering on Tuesday, March 13, at 10 p.m. The story once again centers around heroine Skye Rotter (Lauren McKnight) who is off to college but is waylaid when her younger sister, Alex Bell (Kirsten Prout), decides to have a sweet 16 party. Anyone familiar with these movies knows that is never a good idea. “Since the premiere of the first movie in 2009, the fan-following for Skye’s epic story has continued to grow both in the U.S. and internationally,” said Chris Linn, executive vice president of MTV Production. “We are thrilled to present the exciting final chapter of the trilogy with the original creative team intact.”
