It might come as a surprise, but the only time Spielberg and Streep worked together prior to The Post was almost two decades ago. Streep had provided voice work for Spielberg’s 2000 film A.I. Artificial Intelligence, which only required a day to complete. Apparently, a lot happened in one day, though — Streep ended up referring Spielberg a priest who could exorcise his home.
