Best Hollywood portrayal of the Mass
Many consider this to be the best Hollywood cinematic depiction of the Tridentine Mass, because De Niro, in the role as the priest, gives so accurate a portrayal of a priest doing the rubrics of the Mass. There’s also the inclusion of the Jacob Arcadelt Ave Maria, which is beautifully performed.
It’s from the 1981 film-noir, True Confessions, which is knowing a new audience because it can be downloaded on Netflix.
One of the producers was Robert Chartoff, who also worked with De Niro on Raging Bull.
