Saturday Night Live

NBC | 11:29 pm

Tonight's show is the last new episode before Halloween, which may explain why the host of choice is actor David Harbour, currently best known for his portrayal of grumpy yet heroic chief of police Jim Hopper in the Netflix retro-thriller "Stranger Things." That hit series seems a likely subject for a parody (if not the answer to Hopper's ambiguous fate in the Season 3 "Stranger" finale). The night's musical guest is Cuban-American singer-songwriter and actress Camila Cabello.
