Before directing this film Leo Kraska made a Slender Man based YouTube series called "The Dead Are Watching". You can see some of his inspiration was derived from this series.
In the final scene, actress Laurel Kay Schmidt snagged her hand on the door and it cut her finger as she was exiting the house. Despite the pain she let the scene play out before addressing the wound.
Mr. Empty was created in homage to such films as Evil Dead, Candy Man, Puppet Master, Phantasm and The Dead Next Door. While Mark is leaving his suicide message you can see both Evil Dead and Puppet Master memorabilia out of focus in the background.
Mr. Empty had only one day of production. On that day the lead actor, Pablo, called off and, with no other choice, the Director assumed his role of Mark.
This short film had roughly 10 hours of dedicated Post-Production per a minute of final footage.
