Saturday Night Live

NBC | 10:00 pm

A summer of political developments undoubtedly filled the coffers of this show's writers and performers — and though "Weekend Update" got a primetime run, it's business for real as the late-night staple debuts its 43rd season. Ryan Gosling, whose movie "Blade Runner 2049" is about to open, returns as guest host — with Jay-Z, riding high on the success of his album "4:44," as the musical guest. Alec Baldwin is expected to return as President Donald Trump.
