Chris Brown thinks White actor Joseph Fiennes playing Michael Jackson in an upcoming half-hour comedy is some “corny a** sh*t.” The r&b singer, who has garnered comparisons to Jackson over the years, took to Twitter to slam the casting, tweeting:

Y’all know y’all dead wrong to have dude play MJ. If that’s the case LET ME BE SUPERMAN. Da fuck they do that at? Is that blackface?

Last week, HipHollywood reported that Fiennes would play Jackson in a road trip comedy telling the story of a cross country car ride the pop icon once took with Marlon Brando and Elizabeth Taylor. While alive, Jackson made it clear in an interview with Oprah that he did not want a White man playing him in a film which makes the casting all the more outrageous.
