The characters Kyle and Justin had been conceived as brothers, but Marcus Parker's impressive audition convinced writer/director Mike Stahl to revise his screenplay. He then cast Marcus as Kyle, Justin's adopted brother.
The cast and crew actually camped in the forest during production braving 30 degree temperatures.
The restrooms used in the film are called "Vault Toilets". A plastic commode that sits atop a giant concrete vault that catches all of the waste. They often become very smelly as camping season progresses until they are emptied once the season is over.
