James Corden hosts, live from Los Angeles.
Also this weekend, Alec Baldwin will host "Saturday Night Live" (10:30 p.m., NBC/Ch. 5). I don't think you need to be clarivoyent to know that he won't be getting rave reviews on Twitter from the man in the White House.
Speaking of TV shows that man in the White House won't like, PBS is airing "John Lewis — Get in the Way" (9:30 p.m., PBS/Ch. 7) — a profile of the 76-year-old congressman/civil rights pioneer who was denigrated by Donald Trump after deciding not to attend the inauguration last month.
