This is a movie from the late '50s or early '60s. The scene I remember is of a little boy who lives in a rectortory with priests. He likes to go into the attic where statues and crosses are stored. There is a large cross with Jesus on it. A scene I remember is of the Jesus figure coming to life and holding the little boy in his lap.
