Saturday Night Live

NBC | 11:29 pm

Paul Rudd joins the "Saturday Night Live" Five-Timers Club as he returns to Studio 8-H as the final host of 2021. The actor, who earned high marks for his four previous appearances, stars in the holiday movie comedy "Ghostbusters: Afterlife" and recently was named People magazine's Sexiest Man Alive for 2021, an honor that seems a ripe target for satire in tonight's episode. Rudd also will welcome musical guest Charli XCX, her second "SNL" appearance in that capacity.
