Rarely during the movie do any of the actors portraying Jesus blink their eyes. Director 'Franco Zeffirelli' decided on this as a means of creating a subconscious visual mystique about the character that not only differentiated him from all other characters, and is eerily effective. The boy Jesus in the Temple blinks twice in the Temple, and the adult Jesus blinks only once on film.
The eye makeup for Robert Powell consisted of a thin line of dark blue eyeliner on the upper lid of the eye, and a thin line of white eyeliner on the lower lid. This had the effect of highlighting the piercing blue of the actor's eyes, thus giving him a penetrating stare, when combined with very little blinking, made the character appear surreal and supernatural.
Jesus Christ says "Talitha Cumi" when he brings the girl back to life from her death. Talitha Cumi is Aramaic which means "Little girl, rise." Aramaic was the language of first century Israel. Aramaic continued to be the language of Jews in early second century AD until Simon Bar Kokhba tried to revive Hebrew as the official language of Jews during Bar Kokhba revolt (132-135 AD).
