The OC creator Josh Schwartz is stumped for ideas after the hit show's next season - because the four main characters will be leaving for college. But the producer is optimistic the departure of SETH COHEN (Adam Brody), RYAN ATWOOD (Ben McKenzie), MARISSA COOPER (Mischa Barton) and SUMMER ROBERTS (Rachel Bilson) could open doors for new exciting storylines. He says, "I think we've got at least one more good year in us, so we're going to do some pretty radical stuff at the end of this year. "The season finale is going to be the craziest thing we've ever done and it will launch the show in a whole new direction next year. "So I'm excited about next season. And then beyond, I don't know. We'll see."
