Out of anything you'll see in Tiger, HBO's two-part documentary about golf legend Tiger Woods, the images that'll surprise you most won't be the ones you're familiar with. Not the car crash. Not the mugshot. Nothing from 20 years of Nike commercials. Instead, Tiger's most revealing moments come from a dusty, old VHS tape Woods's first girlfriend, Dina Carvell, gave to Tiger's directors, Matthew Hamachek and Matthew Heineman.
