Jared and Jensen are willing to go beyond 300 episodes:
Quote:
“I am consistently amazed and impressed by our writers and the direction,” Padalecki shared. “I think maybe when I said 300 [episodes], I just didn’t know if we’d keep the quality up, but the quality is higher than it’s ever been. I love the storyline, I love what’s going on with the brothers, with the friends, with the family. So I love being a part of telling the story, and as long as they’re willing to keep picking us up, then count me in.”
Added Ackles: “I will revise that statement and say 300 seems like a nice benchmark” — but not necessarily the final one.
