Three of the main cast members are related in real life.

Cocreators and real-life father and son Eugene and Dan Levy played Johnny and David Rose on the show. 

In 2015, Dan told NPR that he originally just pitched the idea of the show to his dad to see if he might be interested in "fleshing it out and seeing if there was anything there." 

Dan and Eugene's partnership is fairly well-known at this point, but some fans might not have realized that Sarah Levy, Dan's sister and Eugene's daughter, played townie Twyla Sands on "Schitt's Creek."

Chris Elliott made Eugene break character all the time.

In a 2017 interview with Yahoo's "Build" series, Eugene said that Chris (who played Roland Schitt) made him laugh during scenes all the time.

"He's got my number," he said. "He's constantly making me laugh on set … He does it intentionally, of course, and he actually succeeds."
