YMMV / Don't Hang Up

• Magnificent Bastard: "Mr. Lee" is a mysterious hacker who centers in on Sam Fuller, Brady Mannion, and their fellow prank caller friends Jeff Mosley and Roy. Having stalked them over a year, Lee knows all their secrets and weaknesses, using a video of Brady's parents held hostage and killing Roy and Mosley to prove how serious he is while taking control of their electronics and internet. Having already killed Brady's parents, Lee plays the boys against one another by revealing Brady was sleeping with Sam's girlfriend Peyton Grey, switching locations with Mosley's body to ambush Brady, masking him in Lee's outfit and trick Sam into killing him. Lee then reveals the four friends' infamous prank call was to Lee's house, resulting in Lee's wife shooting their young daughter by mistake before killing herself, ending as Lee kills Peyton and frames Sam for everything while escaping.
