'Wet Hot American Summer' TV Series Adds 9 More Stars Including Josh Charles And Randall Park

Camp Firewood is about to get even more crowded. The Wet Hot American Summer Netflix series has just added about 9 more actors, to join the 21 — count 'em — cast members from the original. The new additions include Michaela Watkins, Josh Charles, John Slattery (Mad Men) and Randall Park (The Interview). More details on the Wet Hot American Summer cast after the jump. 

Deadline reported on the new Wet Hot American Summer casting. The list of guest / recurring players includes Watkins, Charles, Slattery, Park, Lake Bell (In a World...), Jayma Mays (Glee), Paul Scheer, Rob Huebel, and Richard Schiff.

Actors set to return from the original include Paul RuddElizabeth BanksBradley CooperAmy PoehlerH. Jon BenjaminMichael Ian BlackJudah FriedlanderJaneane GarofaloNina HellmanKen MarinoZak OrthDavid Hyde PierceJoe LoTruglioChristopher MeloniA.D. MilesMarguerite MoreauMarisa RyanMolly ShannonKevin Sussman, and David Wain (who had a cameo in the movie).

According to the trade, "Watkins will play a tough New Yorker, Charles is a guy from a rival camp, Huebel's a rival professor to Pierce, Schiff is Pierce's academic superior, Park's a librarian in love with Shannon, Scheer is a journalist, and Wain is an acquaintance of one of the main characters from an Israeli kibbutz."

The new casting brings the total count up to 30, so some of these roles are bound to be glorified cameos. The plan for working around the cast's busy schedules involves including only a few actors per scene, not unlike what Arrested Development did with its fourth season on Netflix.

As previously reported, the Wet Hot American Summer TV series will be a prequel to the 2001 movie, despite the fact that many of the cast members playing teens and young adults are well into middle age at this point. Here's Wain's announcement on Twitter, which provides a small clue about the plot.

The Wet Hot American Summer series is created by Showalter and Wain, who wrote the movie. Wain is once again directing. Shooting began last week.
