A brand new revival image reveals that Frasier heads to Cheers' Boston in his Paramount+ reboot. Before Kelsey Grammer's snooty psychiatrist moved to Settle to be with his family, he was based in the East Coast city, where he mingled with the regulars at the Cheers bar. Spending time with the likes of Sam, Carla, and Norm subtly impacted him, making him even just a little like them, resulting in a toned-down version of the character in Frasier. This worked well for his dynamics with his father, Marty, and brother, Niles.
