They tried to be friends, but their chosen paths set them on a collision course. The Clark Kent-Lex Luthor rivalry that fans have long expected finally comes to a head in the 22 episodes of Smallville's Season 6 (2006-7). Former Clark flame Lana Lang (Kristin Kreuk) stuns Clark/Superman (Tom Welling) by marrying Lex (Michael Rosenbaum), and her reason for saying "I do" is just as stunning. But that's not all: Green Arrow (Justin Hartley) forms the Justice League. Will Clark join? Phantom Zone escapees menace Earth. Can Superman stop them? LuthorCorp expands its dark experiments. Will an awesome kryptonite-powered army be the result? The answers, and thrills, are all here in Smallville: Season 6! Extras include a "Green Arrow: The History of the Emerald Archer" featurette; a "Smallville: The Ultimate Fans" documentary; animated "The Oliver Queen Chronicles" mobisodes (mobile episodes) and "The Making of The Oliver Queen Chronicles"; and "Smallville Content Wraps." The latter is an animated series that ran in between the sixth season's episodes, continuing the story line.
