Here's a screen used prop from Exorcist: The Beginning. This was worn by actor James D'Arcy in his role as Priest Francis. "James D'Arcy portrayed the priest who aided Merrin". This is his screen worn wardrobe, and the condition on the piece is quite nice with droppets of Studio blood near the bottom. As well it ties in the back.
The film depicted the tale of Merrin's initial battle with Pazuzu and the rediscovery of his faith, decades prior to saving Regans life in The Exorcist.
A really nice prop from one of the films in The Exorcist Saga. ~Thanks kindly and Gods Blessings~
