The comedy thriller is inspired by a real-life event and follows a realtor, a plumber and a former tennis star whose "lives unexpectedly collide, exposing America’s obsession with true crime, murder and the slow close toilet seat." Cuoco has been cast as Ava Bartley, a married woman. Other plot details and cast information remain unknown.

UCP will serve as the studio, while Rosenberg will serve as showrunner, writer and executive producer. Jason Bateman and Michael Costigan of Aggregate Films will executive produce, with Roxie Rodriguez, also of Aggregate, serving as co-executive producer. Based on a True Story received a straight-to-series order in April. At the time, UCP studio's President Beatrice Springborn said in a statement:

“There are some true stories that are stranger than fiction as is the case for the events that inspire this show. It is a twisted, thrilling and incredibly funny series that combines the comic and suspense talents of the dream team of Craig Rosenberg, Jason Bateman, Michael Costigan and Roxie Rodriguez to create the perfect show for Peacock.”

Rosenberg most recently worked on Amazon's The Boys as a producer and writer.
