Watercooler: Exclusive First Look at Smallville's 200th Episode

OK, Smallvillagers, get ready to fly into a frenzy! On Friday, October 15, the series celebrates its 200th episode, but you can get the party started with this exclusive peek at the official promo for "Homecoming" right here and now. Built around Clark's high-school reunion and featuring the return of James Marsters as a much-less nasty Brianiac, "there are all kinds of nods that go back to the beginning... a lot of glimpses," promises exec producer Kelly Souders, who has also packed in a lot of geeked-out goodies (check out those magazine covers!). And just wait until you see what happens when Clark pays a trip to his future... and runs into himself at the most "Man of Steel" moment the show has thrown at us so far.A second version of this trailer will appear at the end of tonight's "Supergirl" episode on the CW at 8/7c. Check out the video after the jump...
