Movie abour a cancer patient that takes videos for his son…

Hi!
So my friend recommended a movie to me but she couldn’t remember the name.
She said that it was about a man that has cancer and he is looking for someone that would take videos of him for like a week so his son can watch them when he‘s older. That cancer patient is kind of a creep tho and does psychic stuff and has this kind of wolf mask…

she watched the movie last year and said it wasn’t a very old one.
Hope someone can help me 🙂
