As those of you who have been following "The Polka King" movie know the movie has been a blockbuster hit on Netflix. The movie starring Jack Black and Jenny Slate premiered at the Sundance Film Festival in January 22, 2017. Netflix started showing the movie nearly one year later on January 12, 2018. Hollywood Actor Jack Black did a phenomenal job delivering that hallmark Jan Lewan (born Lewandowski) 'Polish' accent. I had the distinct opportunity to attend the premiere in Salt Lake City. And now, crank up the volume on your speaker and get ready to watch Jack Black perform Everybody Polka on NBC Today Show with Savannah Guthrie and Hoda Kotb.
