Matthew Willig first met Dwayne Johnson about a decade ago at an Equinox gym outside Los Angeles. Willig was a fledgling actor, a few years removed from a 14-year career in the NFL trenches. Johnson was ... well, The Rock. The Rock wore a hoodie that day, Willig recalled, surmising the Hollywood megastar wanted to keep a low profile during his workout. They shared a couple of Nautilus machines, and later in the lobby, Willig pulled him aside and requested career advice, the former offensive lineman asking the former defensive lineman about how he could advance his career in show business.
