Use of Latin
In watching this film on TCM, during the scene where Becket is consecrated Archbishop of Canterbury, the Bishop of London says all the prayers in English.
Correct me if I'm wrong, but isn't that a serious goof? At that time (indeed, until the mid-1960's) all prayers would have been recited in Latin.
I presume the producers wanted the audience to understand and didn't want to have subtitles.
