Allison Janney is now an Oscar-winner, making her Hollywood stock rise considerably, so CBS has smartly decided to renew her Chuck Lorre sitcom Mom for a sixth season before she can get lured away by some better offer. Granted, CBS didn’t specifically say that it wanted to keep Janney from running off, but it’d probably be pretty important to any TV network to be able to say it has an Academy Award-winning actress on hand. This news comes from Deadline, which says the network has now renewed its entire current slate of Lorre shows, with The Big Bang Theory and its flashback spin-off Young Sheldon having already been picked up.
