Legendary skateboarder Stacy Peralta directed this fast-paced, award-winning documentary that focuses on the Z-Boys of Venice Beach, Calif., who revolutionized skateboarding in the 1970s when they infused surfing techniques into the sport. Credited with founding skating culture as we know it, these young, innovative guys became legends in the field, and the depth of their influence is still felt in a variety of sports -- and society -- today.
