MTV is doing a slasher movie.

With the network increasing its scripted shows and teen horror continuing to perform well at the box office, MTV has commissioned its first stab at the popular genre.

In My Super Psycho Sweet 16, a privileged teen's birthday bash at a roller rink is interrupted by a serial killer. The title and concept plays off the network's reality hit My Super Sweet 16, which chronicles the lavish birthday parties of pampered kids.

The movie already has been shot and is pretty graphic, according to MTV senior vp production Chris Linn. The network plans to release an uncut, download-to-own version in addition to the edited telecast.

Psycho Sweet 16 is among a trio of films the network is working on that have ties to current series. Also green-lighted is the musical Turn the Beat Around, which centers on a young dancer and ties into the reality show America's Best Dance Crew. The network also is developing a movie version of its reality series Made, about a band nerd who makes the cheerleading squad.
