Grind is a 2003 American skateboarding comedy film directed by Casey La Scala, written and composed by record producer Ralph Sall, starring Mike Vogel, Vince Vieluf, Adam Brody and Joey Kern as four teenage aspiring amateur skateboarders on a road trip from Chicago, Illinois to Santa Monica, California in an attempt to get noticed by pro skateboarding legend, Jimmy Wilson, and get skateboarding sponsorships. It was a critical and box-office bomb.
