All good things must come to an end and next spring, one of those good things coming to an end will be the long-running CW Network series Smallville. We go one-on-one with the stars of the show, including Tom Welling (Clark Kent, Superman), Erica Durance (Lois Lane), Cassidy Freeman (Tess Mercer), executive producer Kelly Souders and a surprise interview with Laura Vandervoort (Kara, Supergirl), for some exclusive video interviews, to reveal secrets about the 10th and final season. Take a look!
