Looks like Big Boi will be making an appearance in Morgan Spurlock's upcoming documentary "The Greatest Movie Ever Sold". The doc looks to be about product placement in films - and it will be entirely funded by product placement.
Most likely, Morgan will be talking to Big about his partnership with Crown Royal Black, but more importantly, we'll get to hear him weigh in on the lines between corporate interests and "Art". Check out the trailer. Daddy Fat Saxxx appears at around 1:55.
