When it comes to acting, Beyoncé can bounce (meaning, take a hike). But Jeffrey Wright, who plays Muddy Waters, can sure enough act, and so can Columbus Short, who plays Little Walker, and Mos Def, who plays Chuck Berry, and Eamonn Walker, who plays Howlin' Wolf. In fact, a very good reason to watch this film is to see Mos Def as Berry and Walker as Wolf. I will even go to the limit and say that Walker as Wolf (the blackest of black men) is more than enough reason to watch this movie about the fast rise and fast fall of a record label that helped launch the rock 'n' roll era in popular music.
