The dialogue in this movie is outstanding, and it’s delivered by some of the top actors of their time. Peter O’Toole as Henry II in particular delivers one of the best dramatic performances of the historical film genre, as exemplified in this scene: https://youtu.be/_u9VmtQUmoM?t=5696

The film is interesting because it shows the background of the phrase “Will no-one rid me of this turbulent priest?” and also because it demonstrates the Norman vs Saxon class distinction in England of that era.
