During our ongoing investigative reporting into the final season of Smallville, we knew it was integral to speak with the brains behind the operation: Executive Producers Kelly Souders and Brian Peterson. Over the course of the last decade, Smallville has shifted from its one-off episode style to an ongoing mystery into the world of Krypton‘s favorite son. This season the mysteries will be resolved.

While the Greeks had Zeus and Athena, in modern times we have our own mythology in the form of superheroes. Like epic poems passed down myths, Smallville illuminates Superman’s origins with dramatic flare. After fighting Lex Luthor, Brainiac, and Zod, you’d think Clark Kent would get a nice vacay. Instead, his hero’s journey will only really begin after the final episode is over.

Yesterday we spoke with Souders and Peterson about episode 200, Kristen Kruek and more. This time we’re talking with the producers about Clark’s legendary journey thus far and what they have in store for our Man of Steel. Note: This interview may contain spoilers. Read at your own risk.

The Flickcast: Smallville’s plot structure has evolved from being a “Freak of the Week” structure to having an ongoing mythology. Can you describe why the choice was made?

Kelly Souders: Well, I think anytime you’re on the air for that long, you have to reinvent it. If not for just that we’d all get bored if we kept doing the same thing, but so that the fans have something new to grow with too. I mean ten years, you change a lot. We change a lot, each fan is going to change.

I think it’s evolving has a lot to do with it surviving. I think we tried to make the show as organic to real life as possible. If we don’t all change, find out new things about ourselves, or try to make changes within ourselves- the same thing would happen (to us) and we’d kind of stall out.

With the last season of Smallville off to a rollicking good start, we snatched up the chance to sit down with Smallville long-time executive producers Kelly Souders and Brian Peterson. While they were a touch shy about spilling the Kryptonite on this season’s surprises, we never-the-less used our super strength to investigate the return of former cast members and historic episode 200 (set to air October 15th).

It seems this season will be strewn with super heroes and villains from across the galaxy.  Giving Kal-El a run for his money, Laura Vandervoort returns in brilliant blue and red style as Supergirl in episode 3, airing October 8th.

The Flickcast: Can you tell us about any plans to bring back favorite cast members from past seasons?

Brian Peterson: Having Annette O’Toole back as Martha Kent and Michael McKean as Perry White- we worked all season to get that to happen. It was fantastic, they were so great, it was such a great episode.

We’d like to, it’s hard because all of these actors, it’s not always up to us, like they have TV shows and careers and theater. You know Glover, we would love to have John Glover back and that man is on Broadway from the beginning of the year until the end of the year.

So, that’s our goal, absolutely, to try to get people like Perry, and Martha Kent, and Lionel Luther back, or at least maybe an appearance.

FC: Last season, Smallville‘s epic episode entitled, “Absolute Justice”, featured the monumental members of the Justice Society. Any talk of a Justice Society spin-off series? Will any members of the Justice Society be making future appearances this season?

BP: I know people are so excited about that and right now, to my knowledge, there are not (spin-off series). I think there’s always opportunities.

But as far as episodes, we’re definitely going to have some of the Justice Leaguers and Justice Society people back in the show for sure (check out episode 2). But as far as a spin-off, I wish that was something I could see into the future and know, but I don’t know.
