As previously reported, producers of the untitled film commenced an open casting call this past Sunday (August 12) in order to find a suitable actor to portray the legendary MC. According to Variety, Fox Searchlight Films has also selected George Tillman Jr., who helmed such films as Soul Food and Men of Honor, to direct the film. "We know he will make a brilliant movie and show the true humanity of Christopher Wallace's character," said Fox president of production Claudia Lewis of Tillman. Also producing the project are Biggie’s former managers Mark Pitts and Wayne Barrow, and the rapper’s mother Voletta Wallace. Production is set to begin in the fall.
