The tentative title of the proposed Irish-language Cheers remake was Teach Seán.
The project was announced in December 2012 after Dublin-based Sideline Productions secured plans to adapt the American sitcom for TG4, Ireland’s Irish-language television channel. Teach Seán was a working title rather than the name of a completed series, which is why the question specifies “tentative.”
The adaptation was intended to preserve the basic Cheers setup while changing its cultural setting. Its central barman would be an Irish former hurling star instead of Sam Malone’s former baseball career. The producers discussed adapting roughly 10 to 12 episodes from the original show’s extensive script library and relocating the action to a town in western Ireland.
The proposal is easy to confuse with ordinary Irish terms for a pub, but the announced title was a character-based name: “Teach Seán,” literally built around Seán’s house or home. The remake was planned for TG4, but it did not become a regular broadcast version of Cheers.
