The longest-running TV series that’s based on a comic book character began on The WB in October 2001. This Friday it’ll kick off its tenth and final season.

The Smallville story centers around a pre-Superman Clark Kent. Stories initially revolve around Clark’s home-life, school, and Smallville community but later shifts to his workplace at The Daily Planet newspaper. Ninth series regulars include: Tom Welling (Clark Kent), Allison Mack (Chloe Sullivan), Erica Durance (Lois Lane), Cassidy Freeman (Tess Mercer), Callum Blue (Zod), and Justin Harley (Oliver Queen/The Green Arrow).

In season nine, villainous survivors of Krypton attempt to take control of Earth, and Clark must fight the growing danger posed by Zod and his warriors. He gets some help from the shape-shifting Wonder Twins, magical Zatanna, and the Justice Society of America’s Dr. Fate, Hawkman and Stargirl. Amidst the threat of annihilation, Clark and Lois’ relationship takes a romantic turn. Could justice, Earth, and love all survive?

The ninth season has just been released on DVD. All 21 action-packed episodes are included on the six DVD set, as well as commentaries on two key episodes, unaired scenes, and two featurettes; Kneel Before Zod!: the Evolution of A Classic Evil Character and Absolute Justice: From Script To Screen, Introducing Venerable Justice Society of America Heroes Into Smallville’s Universe.
