Sasha Grey has been cast as an evil villain mastermind named Viola DeWynter, and ironically her character looks extremely like the actress. This is one of those admirable villians if you are a big Sasha Grey fan.
Hulk Hogan has been cast as pro wrestler Angel De LaMuert whom is leader of a street gang called the Lucadores. What makes this great is you can probably expect to hear quite a bit from Hogan in Saint Row The Third as the role indeed sounds pivotal to the plot.
Addtionally Daniel Dae Kim will be reprising his role as Johnny Gat, the chief lieutenant of the Third Street Saints. Johnny is your closest comrade and assists you throughout the entire Saints Row the Third experience.
