Castle - Unofficially Renewed for an 8th Season

As for another of ABC’s longer-running dramas, Lee told me that with Nathan Fillion and Stana Katic’s contracts due to expire this spring, “We love Castle, we love those two, and we want to see Castle on the air for many years to come.” Though not officially announcing a Season 8 renewal, he ventured to say, “It will be coming back.”
