"High School Musical" star Ashley Tisdale is making her feature-film debut in a coming-of-age comedy but it won't be seen on the big screen. The movie, called "Picture This," is going straight to DVD.

The film, which will be released July 22, is part of the new direct-to-video movement from MGM DTV. The company entered the direct-to-video business in January 2007 and aims at attracting young and men women to the movie because the title is familiar or the cast is appealing to them.

Enter Tisdale, who also appears on the Disney Channel's "The Suite Life of Zack & Cody." The star liked the script and agreed to do the project.

In the film, Tisdale plays an unpopular high school senior who gets a date to the biggest party of the year with the school's most sought-after guy, only to find herself grounded on the appointed date. So she enlists her friends and video phone to outsmart her dad, as well as her date's ex-girlfriend.
