For this conversation, Kristen Wiig and Jon Hamm reunited only two weeks after appearing together on “Saturday Night Live” — Wiig, a regular on the show from 2005 to 2012, joined the Five-Timers Club as the host, and Hamm, her co-star in “Bridesmaids,” appeared as a special guest. The pair had plenty to celebrate: This past season, Wiig starred as a would-be socialite trying to claw her way into the in crowd on Apple TV+’s “Palm Royale.” Hamm also played a gleefully ambitious character for Apple, as an Elon Musk-type billionaire attempting to become a media mogul on the third season of “The Morning Show.” But an even bigger turn came with Noah Hawley’s “Fargo” from FX, where his devious Sheriff Roy Tillman runs roughshod over all those in his way — after making a very memorable entrance.
