In Argo, who is the voice for the prologue?
Milla Jovovich. it's not credited but I'll bet every dime I have that it is her.
In the movie Argo, the voice for the prologue was by a narrator whose name is not revealed. She is just referred to as 'the narrator'. This movie was directed by Ben Affleck. See http://www.imdb.com/title/tt1024648/.
In the credits, Huma Abedin (politician Anthony Weiner's wife) is thanked first. I'm pretty sure the narrator is Huma.
Sheila Vand is the narrator. she also plays the housekeeper who suspects the guests are americans.
Its Jennifer Garner, his wife
