 Harvey Stephens, as Damien, was largely chosen for this role from  the way he attacked Richard Donner during auditions. Donner asked  all the little boys to "come at him" as if they were attacking  Katherine Thorn during the church wedding scene. Stephens screamed  and clawed at Donners face, and kicked him in the groin during his  act. Donner whipped the kid off him, ordered the kids blond hair  dyed black and cast him as Damien.
