The 85 y.o. (at the time of filming) actress, Heftzigul Shmuelov-Osherov ("Grandmother"), is really the maternal grandmother of the creators and the main actors of "Where Do You Live?", Hay and Ronen Davidov. Never acting before, she was elected by the director (Yaron Shilon), for her genuine behaving before the camera and her ability of learning texts.
