Along with Murphy, Usher is in talks to play the Godfather of Soul according to Brown's daughter, Dr. Yanna Brown. Before his legal troubles, Wesley Snipes was considered the casting pool forerunner and in the past, Dr. Yanna Brown has suggested that Chris Brown would also be a good choice for the role. (No comment.)
Usher's IMDB acting credits include Sabrina, the Teenage Witch, 7th Heaven and most recently, the critically-reviled Katherine Heigl/Ashton Kutcher comedy Killers. Meanwhile, Eddie Murphy earned an Oscar nomination in 2007 for his impressive performance in Dreamgirls. So, yeah.
Spike Lee has been vocal about having his lead actor lip sync Brown's songs. No word yet on whether this would change if a musician scores the role.
