Amy Seimetz (The Girlfriend Experience) has joined the cast of Mating, Showtime’s half-hour comedy pilot from Jason Katims and Stu Zicherman and starring Taran Killam and Jim Belushi.

Mating (working title) centers on Jay (Killam), a recently divorced guy who married young and now finds himself completely unprepared for the brave new, frank and fluid world of dating and hooking up. Seimetz will play Lexi, whose trust Jay is trying to earn back. She will be a series regular if the show is picked up.

Written and executive produced by Zicherman, the project is an “annual anthology” as each season will focus on a different protagonist’s journey through modern dating and relationships. True Jack Prods.’ Katims and Michelle Lee executive produce with Zicherman for Showtime and Universal TV. Craig Johnson (The Skeleton Twins) executive produces and will direct the pilot.

Seimetz co-created and appeared on Starz’s The Girlfriend Experience, and other recent credits include Stranger Things, The Killing and Halt and Catch Fire, which today was renewed for a fourth and final season on AMC. She next is on the big screen in Mercy and Alien: Covenant. Seimetz is repped by WME and One Entertainment.
