For the iZombie uninitiated, Rose McIver plays Liv, a zombie coroner who eats the brains of the bodies that come through her morgue to satiate her appetite for human flesh. In doing so, she’s able to (temporarily) absorb their character traits and memories. The show’s mythos raises a lot of questions, the least important but most enjoyable of which is, what celebrity brain would you eat if given the chance? We asked McIver and her castmates in the video above.
