The already large ensemble cast of Netflix’s limited series Wet Hot American Summer is getting larger. I’ve learned that several new faces are set to join the dozen original cast members in the eight-part series from Michael Showalter and David Wain. I hear the list of guest-starring/recurring players includes Trophy Wife and SNL alumna Michaela Watkins; Mad Men‘s John Slattery; Randall Park, who is riding a wave of publicity over his role as Kim Jong-un in The Interview; Jayma Mays; Lake Bell; Paul Scheer; Rob Huebel; and Richard Schiff. Wain, who had an uncredited cameo in the movie, also will have a part on the show.

He joins returning cast member Showalter, who will be reprising his role along with Elizabeth Banks, H. Jon Benjamin, Michael Ian Black, Bradley Cooper, Judah Friedlander, Janeane Garofalo, Nina Hellman, Ken Marino, Zak Orth, David Hyde Pierce, Joe LoTruglio, Christopher Meloni, A.D. Miles, Marguerite Moreau, Amy Poehler, Paul Rudd, Marisa Ryan, Molly Shannon and Kevin Sussman.

The 2001 cult film was set on the last day at a fictional Jewish summer camp in 1981. I hear the show is set on the first day of the camp. I hear 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. Netflix declined comment.

Showalter and Wain — who wrote the movie — created the limited series, with Wain reprising directing duties and Showalter serving as showrunner.
