writer/director/producer/tech and sound supervisor

Writer/director Sam Kellman has been storytelling for as long as he can remember. Over the years, he has pursued various avenues to tell these stories, mostly leaning into filmmaking and immersive entertainment as preferred mediums. He recently founded his indie production company, Inside the Box, in 2020.


His short films have screened at over 15 film festivals over the course of high school alone (including Seattle International Film Festival, All American High School Film Festival, NFFTY, WestFlix, and more), garnering over 30 individual awards and nominations. In 2021, he was honored to direct a TV bumper for Syfy's CHUCKY series.

He broke into immersive entertainment with his annual Halloween event, The Opechee Haunt, having put on 13 different experiences under the name, including TOUR, The Donnie Darko Experience, and Jack's Halloween JamBOOree. These experiences ranged from your more traditional walkthrough haunted houses to full immersive theatre shows and everything in between. The annual attraction was profiled in the 2018 documentary Epic Home Haunts, and has been covered by a multitude of media outlets, including LA Weekly, OC Weekly,, Westcoaster, and Hollywood Gothique, just to name a few. The event has also received praise from John Murdy and Michael Aiello of Universal's Halloween Horror Nights, and Criminal Minds star Matthew Gray Gubler. 

Sam turns 20 this year, and Within Our Walls is his first venture into the "pro" world, orchestrating an event at a truly independent venue. It's extremely exciting, and he cannot wait for you to experience this waking nightmare for yourselves.
