The King of Kong is a new documentary coming out later this year. It focuses on classic gaming and specifically a Justin Wong-like Donkey Kong player who comes out of nowhere to challenge the world record holder, Billy Mitchell, who you may remember from those Mtv or VH1 specials - the guy who looked like Jesus who had the hot sauce business.
