The writer-director was partially inspired by a close friend who died of ALS, but ultimatley lost a scene involving the affliction: "That's definitely one that hurt when I took it out."

Wolf Man director Leigh Whannell has explained the horror film's end credits tribute and the personal story behind it. The latest incarnation of the classic movie monster features Christopher Abbott and Julia Garner as a couple who are attacked by a vicious creature, one that can cause its victims to transform into something just as horrifying.

"I think if you want to make anything scarier just go with something familiar," said Garner in a recent interview with ScreenRant.
