Friday Night Lights' realism translates into its characters being written off the series when the time naturally comes for the youngsters to leave Dillon, Texas.

But might we see some old faces return later on?

Of his future with Friday Night Lights, Scott Porter, whose character Jason Street was a central component of Seasons 1 and 2 but left town last year, says:

"I may have a guest spot return to Dillon in Season 5. In the final episodes of the wrap-up season, we'll put a bow on everybody. There are definitely some ways to bring Jason Street back."

"If Tim Riggins gets in trouble, or if Riggins ends up getting married, then I'll come back for that. [Street's return] is probably going to be Riggins-related, although since I'm a football scout now, I could probably come down and look at some of the new kids at East Dillon."

Friday Night Lights has been picked up for two seasons, with the next beginning this fall on DirecTV. However, the stars have stated that those two will be the last.

For now, Scott Porter filmed a Fox pilot called Masterwork about international art theft. It was filmed on location in Europe, and Porter plays an FBI agent.
