Chad Coleman, best known for playing Dennis “Cutty” Wise on the HBO series The Wire and as Tyreese on the AMC series The Walking Dead, went on a rant while in the New York City subway recently.

Coleman was apparently yelling at passengers on the Downtown 4 train on Friday, screaming “I wanna know where my humanitarians are,” announcing that he was indeed the guy from the Walking Dead and The Wire, according to media reports.

He ranted about humanitarians and spent over three minutes, which was caught on video — Coleman even said people can send the film to TMZ if they want.

Why was he ranting? Apparently people on the train were trying to figure out who he was, and he heard a guy said, “No, we don’t know that n—r,” which set him off, the actor said to TMZ.
