Watch full movie online. Once the hottest comic in America, Hollaback's name was in hip-hop songs, all over the media making Eminem look like MC Hammer. Then, in a flash, it's gone. He's played out. It's so bad that even the places he used to headline won't let him in the door. Well, Hollaback isn't going to take it. He's not about to let his fifteen minutes of fame slip away while getting booed off the stage. No one better diss Holla... it may cost them their life.
