Mckenna Grace Instagram – After I screen tested for Ghostbusters, Ivan came over, smiled and patted me on the head. I remember wanting to ask for a photo so badly and thinking it may be my only chance, but I had to act professional. I had no idea what a big part of my life him, his family and Ghostbusters would become. I inherited a huge GB family all over the world when I got the chance to play Phoebe…I owe so much of that to Ivan Reitman and the legacy he created. He was a set grandfather to us all, caring and kind—to make him and Jason proud meant and means so much…thinking about them and the whole Reitman family.
