Fifteen guest stars have been added to the TV adaptation of The Earliest Show, with Chris Pratt, Sarah Silverman and Lamorne Morris among the names confirmed on July 29 by Deadline.

The full guest roster runs wide. Pratt and Morris are joined by Gillian Jacobs, Nicole Byer, K Callan, Mary Holland, Kerri Kenney-Silver, Majeed Nami, Jillian Bell, Tawny Newsome, Gil Ozeri, Nate Smith, Drew Tarver and Samara Weaving. That is 15 in total, all confirmed in the same Deadline report.

Ben Schwartz and Lauren Lapkus, who created and starred in the original digital series, are back. They reprise their roles as Josh Bath and Samantha Newman. Schwartz is writing and directing every episode, and both he and Lapkus serve as executive producers.

The original The Earliest Show launched on Funny or Die in 2016 as a comedic look behind the scenes at the earliest live morning show in upstate New York. It was Emmy-nominated. The TV adaptation expands that premise into a full series.

Four cast members were already on board before this latest announcement: Kevin Carroll, Ryan Gaul, Henry Winkler and Brandon Scott Jones. Their involvement was reported in earlier coverage cited by Deadline.

The production model is unusual. Amplify Pictures and Stay Tuned are fully co-financing the series as an independent production, meaning no network or streaming platform is attached as a commissioning partner. Irony Point and Funny or Die are also attached, with Irony Point's Daniel Powell and Alex Bach overseeing physical production. A series made without a platform committed in advance is a path more common in film than television, and it means the show will seek a buyer once it is ready rather than being ordered straight to series.

For fans of the original, the adaptation brings the core duo back with a sprawling guest cast that pulls from comedy, drama and everything between. Pratt's involvement alone will draw attention, given his profile in both film and television. Silverman, Byer, Bell and Newsome bring deep stand-up and sketch credentials. Holland, Tarver and Schwartz himself are veterans of the improv-to-television pipeline. Weaving adds a film presence, and Kerri Kenney-Silver ties the project to one of comedy's most influential ensemble traditions.

No release date, episode count or platform has been announced. The series is still in production.
