Quick — name the NBA‘s all-time scoring leader. Hint: It’s not Michael Jordan. Production has begun on an HBO documentary about Kareem Abdul-Jabbar, the LA hoops legend who won multiple championships with the Lakers and UCLA Bruins en route to the Basketball Hall of Fame. Aside from being one of the most dominant basketball players of all time at the high school, college and pro levels, the gentle giant born Lew Alcindor has been an outspoken defender and critic of political and cultural matters. He also is an author, columnist, part-time actor — think Airplane! and fighting Bruce Lee in Game Of Death — and 2012 appointee as Cultural Ambassador for the United States. Ron Yassen is directing the untitled film from HBO Sports and Mandalay Sports Media, in association with Iconomy Multi-Media and Entertainment. It is being produced by Deborah Morales, whose credits include On The Shoulders Of Giants, the 2011 docu Abdul-Jabbar co-wrote that spotlights the Harlem Rens, a dominant all-black hoops team of the 1930s. Mike Tollin is exec producing. HBO Sports President said of Abdul-Jabbar, “While he has lived so much of his life in the media spotlight, his extraordinary story has never been explored in depth, and we are grateful to Kareem and his team for allowing us to bring his story to life.” The news comes days after Abdul-Jabbar appeared on HBO’s Real Time With Bill Maher.
