Jenny Slate is set to co-star with Jack Black in the indie comedy “The Polka King.”

Jason Schwartzman and Jacki Weaver are also on board. “Infinitely Polar Bear” writer and director duo Maya Forbes and Wally Wolodarsky are writing and directing.

The pic is based on the Joshua Brown and John Mikulak documentary, “The Man Who Would be Polka King,” following the rise and fall of Jan Lewan, a Pennsylvania polka sensation who shocked the polka world when it was revealed he seduced his fans into investing in a Ponzi scheme.

Black, David Permut, Stuart Cornfeld, Shivani Rawat, Monica Levinson and Priyanka Mattoo are producing. Rawat’s ShivHans Pictures is also financing “The Polka King.”

Slate has several films set to debut in the next year. She will star opposite Chris Evans in Marc Webb’s “Gifted,” which opens next April; “My Blind Brother,” which also stars Adam Scott; and “Brain on Fire,” which also stars Chloe Moretz.

She most recently lent her voice to the Illumination blockbuster “The Secret Life of Pets.” She is repped by WME and 3 Arts.
