Youth is wasted on the young, some say. Well, in “Pretty Wise,” the new film by People Films, it certainly appears like the crop of 11 rising stars (along with three veterans) are effectively putting their early years and blossoming talent to good use. Hitting the city streets from Quebec to Anchorage, the backcountry powder in Whistler and Montana, and then Austria, Mt. Baker, Japan and Mammoth, as well, along the way, the spotlight is shined on faces you’ve certainly seen but maybe not yet been able to identify. Theirs are names and faces you better get to know.
