1/29/18. Jack Black seems to have a knack for playing real life creeps, like Bernie Tiede in Bernie, the undertaker who embezzled $3 million from a wealthy widow after killing her. In this movie, Black plays the con artist, Jan Lewan, a Polka entertainer who pulled a Bernie Madoff on his many unsuspecting fans. Lewan sucked millions from people who were entranced by his ebullient personality. Black did a great job with this role.
