Image Credit: Stephen Lovekin/Getty ImagesThe networks have been ona pilot-greenlighting tear lately.

But which possible show has the potential to be a gem of the 2011-12 season?

But alas, the potential seems to be there withRinger.

Are you dying for more details?

), and why the show is indeed a good fit for CBS.

WHAT ISRINGEREXACTLY?Its a thriller, for sure, Traugott explains.

Its an edgy thriller about redemption and about revenge.

Theres a point of view of two twin sisters who grew apart over a tragedy in their past.

And one now seeks redemption and the other one seeks revenge.

The sister who is seeking redemption has had a much more troubled life.

When her fancy pants sister disappears, she takes over her life.

Her sister dies in a boating accident.

WHY CAST SARAH MICHELLE GELLAR?

In part just because of the subject matter youre able to do in cable.

Both places are great.

Sarahs manager got it to her, and she fell in love with the piece, too.

We had been talking about this group for over a year trying to figure this out.

DOES GELLAR PLAY BOTH SISTERS ROLES?Yes!

She plays two characters: One is Bridget, the sister who takes over Siobhans lifeSiobhans the other sister.

The sisters reunite after having been estranged for a long time, and when they reunite, Siobhan dies.

She falls…you know, in a boating accident.

So its like Hayley Mills of Lindsay Lohan inThe Parent Trapand its more modern remake?

Yeah, Traugott admit, with a laugh.

Thats kind of a comedic reference, and a reference old old Westernsyeah, Sarahs playing both roles.

IF SIOBHAN DIES EARLY, DO WE SEE HER IN FLASHBACKSOR WHAT?Yes, exactly.

Youll see her that way.

Not necessarily tonally nor stylistically, but the show comparable toDamages.

Not just flashbacks but through actual stories in the past.

Thats whats happening here.

WILLBUFFYFANS BE PLEASED WITH THIS ROLE FOR GELLAR?Duh: yes!

For theBuffyfans, she wanted part of what she initiated.

And we think this show has that quality to it.

HOW WILL THIS PLEASEBUFFYFANS EXACTLY?Its a very different show.

I mean,Buffyis so specific and a great, cool genre piece, Traugott says.

Thats what were looking for.

And thats what we were looking for in this.

IS GELLARS BRIDGET SUPPOSED TO BE A HEROINE?Its not like that, no, Traugott clarifies.

I wouldnt say that.

Its not that kind of a show.

Its more of a thriller.

Very different from theBuffycharacter, but theres a lot there for the audience to grab onto.

Shell be dealing with Siobhans friends, and theyll be trying to kind of safe-crack this mystery.

WHAT OPENED THE DOOR FOR A SHOW LIKE THIS ON CBS?

Hopefully, if we do it right,Ringercan be the next evolution of that.

That is, on paper its not necessarily a CBS show but worked exceedingly well in thatGood Wifeway.

All of our stuff is starting now.

The goal would be to shootyou know, like all the other pilotssometime in early to mid March.

WHY IS GELLAR PERFECT FOR THIS ROLE?Im just a fan of Sarahs, Traugott says.

It seems like America wants to, and it seems like CBS was a fan from what I saw.

Hopefully if we do our jobs right well have an opportunity.
