The first trailer for Spike Lee's BlacKkKlansman has arrived. The film is based on a true story of an African-American cop who went undercover to infiltrate the Ku Klux Klan. Based on the trailer, it appears Lee has managed to make both a fun and entertaining buddy cop movie and a topical and political film that he's built his career on. I haven't been this excited for a Spike Lee joint in years. BlacKkKlansman opens August 10.
