Richard Jenkins has joined the cast of the upcoming HBO limited series “DTF St. Louis,” Variety has learned exclusively.

Jenkins will appear in the series alongside previously announced leads Jason Bateman, David Harbour, and Linda Cardelinni. The show was picked up for seven episodes at HBO back in November and is now in pre-production.
