On the last day of filming, it was very stressful. We had a lot of scheduling problems and ultimately Melina was unable to join Sarah and me. Since Melina was the editor and we were done with all the stalker scenes, it was okay for her to be there. The only thing that completely slipped my mind was that Melina was the one who had the landline. So Sarah and I had to improvise. We ended up using a remote control to be the phone.
I then filmed the other side of Sarah's face so her head would block the fact that we are using a remote as a phone.
