Just to be a bit of a movie critic…
Well, the laying down of the tiara seemed right since it is not used.
Also, the altar looked wrong with the crucifix facing the camera with six modern candle holders. Also, since he was Eastern Rite, I would think he would use Eastern Mass vestments as opposed to Roman vestments. Also, the papal announcement was incorrect by not announcing the name of the pope. He also should have said the whole benediction and not just the last part.
I did not like him wearing the suite and tie. I didn’t like the sneaking off thing he did at some point in the movie.
What bothers me is that Pope Kiril pledged all the Church’s property and possesion for charity. I wonder if that meant there would be no St. Peter’s Basilica, no parish churches (land owned by the Church).
Anyway, despite some issues, I liked the movie.
By the way, why did he pray in the orans position with his fingers in a certain position? Is that an Eastern Rite thing too?
