Its a full-circle moment thats really nice.

My first thought was like, Really?

Her first day back onSmallvilles Kent Farm set with Welling was weird, but in a good way.

It was bizarre [because] it felt like we hadnt missed a beat, Durance says.

It was just easy.

SMALLVILLE

It was like coming back in and working with family.

So it was very, very cool.

As aSmallvillefan, Guggenheim was delighted seeing them on screen again.

Every turn, every nuance, every little choice is just so perfect, he says.

Having been writers onSmallville, I stepped aside and let them speak to where things were headed.

As a fan of the show, it answered a lot of questions that I had.

It provided a lot of closure, I think, in a really nice way.

Even though the story was crafted bySmallvillevets, Guggenheim did share a scene withSmallvilleco-creator Alfred Gough before filming began.

Says Guggenheim: I wouldnt say he blessed it, necessarily, but he described it as something fun.
