If you don’t yet have plans for a wildly entertaining New Year’s Eve, TCM provides one tonight – and it’s one that keeps going long after other New Year’s Eve festivities have concluded. Starting at 8 p.m. ET, TCM presents a quintet of full-length movie compilations of highlights from other movies. First up is 1974’s That’s Entertainment!, a breathless but proud romp through the golden era of MGM musicals. That’s followed at 10:30 p.m. ET by 1976’s That’s Entertainment! II, and at 12:45 a.m. ET, the first full movie shown in TCM’s New Year of 2019, the 1994 compilation That’s Entertainment! III. But wait, as they say on TV, there’s more. At 3 a.m. ET, there’s a showing of 1985’s That’s Dancing! – and at 5 a.m. ET, the overnight salute brings up the first dawn of 2019 with 1976’s It’s Showtime, a look at famous Hollywood and related show biz animal acts.
