It is a subject that has been debated among Smallville fans for years: A significant number of them insist that Tom Welling would have done the whole “Superman costume” thing in the 2011 Smallville series finale if that was asked of him.

Now, six years later, Tom did a fairly extensive interview with Entertainment Weekly where he talks about the reasons why he did not want to.

“It was something that we discussed before we ever shot the pilot with [creators] Al [Gough] and Miles [Millar],” Welling told EW about the genesis of the whole “no flights, no tights” thing that brought him to the series. “We literally had a sit down where we talked about the show and I asked about the suit and the tights and the flying, and they said, ‘No, absolutely not,’ part of the reason being is that show is about a teenager trying to figure out who he is. They felt that once Clark put on the cape and the suit, life became too easy, in a sense. They wanted to focus on who this character was before that. And, at the time, because of where visual effects and special effects and stunts were, it would be too expensive. That’s mainly why they save that for movies, more or less.”

As for the series finale, which gave fans only a shirt-rip that left many disappointed, Welling wouldn’t say it was his decision, but it sounds a lot like it. “It was literally something that the entire series was behind in not doing that,” he said. “We did things on that show where we didn’t call them powers, we called them abilities — you weren’t allowed to say powers; you just weren’t because Clark didn’t know they were powers, he just knew he had those abilities, so little things like kept us grounded and kept us faced onto the story we were telling about this character, not what he could do with these abilities.”

Welling also dropped the bombshell that there was an idea for Clark to suit up earlier in the series finale, where we’d see full-on Superman, and he was instrumental in making suer it didn’t happen. “Our series finale was supposed to be, in the first act, Clark puts on the suit and flies around, saves Lois on a plane, and does this other stuff,” Welling revealed. “It was a call that I had with Peter Roth, who is the head of Warner Bros. Television, who’s a good friend of mine and we have a great relationship. I said, ‘That’s not our show, Peter.’ He’s like, ‘No, it’s going to be great,’ and I go, ‘Yeah, but just think about what we’ve been doing. If we just jump into that, we haven’t earned it.’”

In the end, the actor was happy with the decision they made to end with a shirt rip. “We jumped onto this idea that at the end of the show, the idea is that Clark becomes Superman and he’s out there, and we know he’s out there, but we can’t go with him, but that we know and we feel good that he’s out there doing good,” he said. “That was what we strove for, and I think we hit it. I liked the ending of the series, because it’s like, ‘Yes, he did it!’ I hope the audience didn’t feel like we didn’t show them something that they needed to see. I felt like we gave them the jumping off point for their imagination as to what could happen.”
