Waking Up Wally: The Walter Gretzky Story (2005)

As a coach and mentor, Walter Gretzky was instrumental in nurturing the talent of his son, hockey great Wayne Gretzky. So it came as an ironic tragedy when in 1991, just days after his 53rd birthday, Walter suffered a debilitating stroke that left him with no memory of his son's hockey career or his own role in Wayne's achievements.
