Luckily, Kelsey Grammer (aka Frasier Crane) shared his thoughts on the matter!
"We tried to do a 'Cheers' reunion on 'Frasier,' [but] they weren't particularly crazy about the idea," Kelsey tells Rach. "So I think that ship has sailed."
While there's no "Cheers" reboot in sight, Kelsey does have hopes to keep directing. He directed about 30 episodes of "Frasier" and various pilots and says he truly enjoys it.
