Wilson was born in Philadelphia, Pennsylvania, and raised in nearby Wayne, Pennsylvania. While attending Radnor High School, he was involved in dramatic arts;  was president of the debate team, where his partner was future New York Times columnist David Brooks, and played tuba in the high school band and was drum major of his marching band. He studied international politics at Arizona State University. Wilson attended the American Academy of Dramatic Arts in New York City. While in New York, he got his first "real" stage experience as a comedian. Wilson is a painter.  Many of his paintings focus on classic children's toys. In 2006, he was selected to join the California Featured Artist Series at Disneyland. Wilson practices Catholicism, and released a Contemporary Christian album in 2000 called In the Name of the Father. With the rise in popularity of the Back to the Future series, many people began to ask him questions about his experiences making the films. Wilson found the repetitive nature of the questions to be so amusing and annoying that he wrote a song about them titled "Biff's Question Song" which he features regularly in his stand-up routine.
