"The Polka King" was released in 2017 and stars Jack Black as Jan Lewan, alongside Jenny Slate as Marla Lewan. Upon its release, the film received mixed to positive reviews, with critics appreciating Black's performance and the quirky true-crime story, but some feeling the film didn't fully capitalize on its comedic potential. Over time, however, "The Polka King" has gained a devoted following and is often regarded as an underrated gem, celebrated for its unique blend of humor and heartfelt storytelling. It has not quite reached the status of a cult classic but is held in higher esteem now than at its original release.
