The first draft was written in 1 hour.
Marcus is an avid horror fan and always wanted to create a horror film from a young age.
Marcus was motivated by the number of people who ignored him when suffering depression in 2018 to create a message of being compassionate toward others when they're in crying out or clearly in pain for "The Shattering".
Nadiya Khan was cast at the audition room to play the villain because she genuinely scared Marcus with her performance.
Marcus had no idea he had an all-female cast until 1 week prior to filming.
