The movie is based on the viral clip "webcam", produced by a german student graduate
The short film Webcam was nominated for the Vimeo Awards in 2012. It was created by ZBros Production (Stefan Haverkamp, Jan Jaworksi, Branden Kramer and Thomas Kropp).
In Ashley Benson's hit tv show Pretty Little Liars, her character is also constantly stalked by an anonymous person (going by the name of "A").
The movie is very similar to the MTV show 'Eye Candy'
