Remember about the rumor that the Batman going to show up in a special episode of Smallville? Well, back in October, the writer and the director of the episode, Steven DeKnight, already denies that rumor.
Now, it's Al Gough's turn to confirm that Batman will not show up on Smallville. The Smallville cocreator said the following, according to TV Guide :
"Yeah, I know, I saw the rumor as well," he chuckles. "It's not happening."
While I like to see how Batman going to be portrayed on Smallville, I think when Superman is still in his hometown, not in Metropolis, Bruce Wayne would be somewhere in Asia, learning ninja skills with Ducard.
