Warner is a graduate of Columbia College Chicago, where he majored in writing & directing. As a junior, he was handpicked for the school’s Practicum program, becoming one of four students to direct a short film funded by the school. He’s also had work performed at the UCB Theatre in Los Angeles. His short film, The Annual Taylor Thanksgiving Day Ping Pong Tournament, was selected into multiple film festivals and screened at the Cannes Short Film Corner.

Ever since he was a child, Warner Nieborg dreamed of doing two things: Making movies and traveling to Saturn. As he grew older, he soon came to see that one of those dreams was pretty much impossible. Accepting that harsh truth, he decided to pursue his fallback option instead.

After a decade of training in the NASA Astronaut Corps, where he set several records and was considered "probably the best astronaut since Neil Armstrong", he learned that the Saturn mission was going to be shut down as the planet couldn’t afford to lose him if something went wrong. With his Saturn dreams canned, he decided to take up film, which he's been at ever since.
