After ten seasons, you might think that, but - maybe not!
OnTheRedCarpet.com caught up with Welling at the 2nd Annual SAG Golf Classic and asked the actor about the super CW show.
Welling stated he didn't have any regrets - yet - and when asked about doing a Smallville movie said there was talk about doing one between season 3 and 4, but there wasn't time. He said it would have been a transition movie for the characters.
"It would've been fun to do a transition movie for those characters. But who knows in the future," said Welling.
Speaking of the future, Welling was asked if he would do a Smallville movie.
"Sure, I don't see why not," Welling said.
Welling also commented on the new Superman reboot coming up from Zack Snyder, the Man of Steel, that stars Henry Cavill.
"They have other plans for Superman, which I'm a big fan of and I can't wait to see what they do," stated Welling.
So would a Smallville movie be a good idea? And if the movie is ever green-lit, does that mean we would finally see Welling in the Superman costume?!
