Chad L. Coleman put on the performance of his life on an NYC subway, except none of it was acting.

“The Walking Dead” actor started screaming at passengers on the Downtown 4 express train on Friday.

“I wanna know where my humanitarians are!” he yelled as he walked up and down the train cart. “Yes, I am Chad L. Coleman. I am on ‘The Wire,’ ‘The Walking Dead,’ I’m not trying to f–k with you. I’m telling you the truth.”

The entire fit, in which he repeatedly yells about humanitarians and identifies himself as an actor, lasted over 3 minutes and was caught entirely on film. Coleman even tells riders to record the video for TMZ if they want.

The actor told TMZ the rant began after people were trying to figure out who he was on a train and heard a guy say, “No, we don’t know that n—-r.” His humanity comments, he said, were in reference to Baltimore.

Coleman is most widely known for playing Tyreese on “The Walking Dead” and Cutty on “The Wire.”

His rep did not immediately return a request for comment.
