Comedian and pilot Nathan Fielder appeared on CNN, where he discussed his experience flying a Boeing 737 during the season 2 finale of HBO's "The Rehearsal."

Fielder, who is the star, writer, director, and executive producer of the series, spent two years training to become a licensed commercial pilot type-rated to fly a 737. During the Season 2 finale, Fielder flew an actual 737 filled with 150 actors. (IndieWire has an explainer about just how Fielder was able to pull that off.)
