Leo Howard did almost all of his own stunts on the show.

Leo Howard (Jack) is actually a black belt in real life.

Leo Howard, Dylan Riley Snyder, Jason Earles, and Mateo Arias are the only cast members to appear in all episodes of Kickin' It.

Despite being credited, Olivia Holt is missing from several episodes due to her making Girl Vs. Monster (2012) in real life. No explanation was ever given for "Kim Crawford's" absence.

Jason Earles acted alongside Mateo Arias' brother in the Disney Channel series Hannah Montana (2006), in which Mateo made a cameo appearance on one episode.
