6 things you have to watch on TV this weekend
Ruth Wilson stars in a new thriller, Jacob Elordi hosts SNL, and more

Welcome to the weekend edition of What’s On. Here are the big things happening on TV from Friday, January 19 to Sunday, January 21. All times are Eastern. [Note: The weekly edition of What’s On publishes on Sundays.]
1. Ruth Wilson leads The Woman In The Wall
Paramount+, Friday, 3:01 a.m.: Six-part Irish thriller The Woman In The Wall makes its way to the U.S. thanks to Paramount+ and Showtime. Ruth Wilson plays Lorna Brady, a woman with PTSD who wakes up one night to find a dead body in her house, leading to a clash with Detective Colman Akande (Daryl McCormack). Here’s a bit from The A.V. Club’s review:
Ruth Wilson (The Affair, His Dark Materials) is a bloody-minded marvel. She embodies a woman imploding while awake and exploding while asleep. Lorna has a haunted, haggard look through most of the series; her body is falling apart from stress and lack of sleep. No actorly vanity here.
2. Saturday Night Live returns
NBC, 11:30 p.m.: Saturday Night Live kicks off its 2024 run with arguably one of the buzziest stars going. Priscilla and Saltburn’s Jacob Elordi hosts the show’s season-49 return, with Renée Rapp (a.k.a. Mean Girls’ Regina George) gracing the studio as musical guest.
