- Dueling-Stars Movie: It is Richard Burton, one of the most talented actors, co-starring with Peter O'Toole.
- Ensemble Dark Horse: Richard Burton as Becket, a rare occasion for the title character to be this. As One-Scene Wonder shows, John Gielgud as Louis also reached this status. Donald Wolfit as Bishop Folliot, David Weston as Brother John, Pamela Brown as Eleanor of Aquitaine, Geoffrey Bayldon as Brother Philip, Riggs O'Hara as Prince Henry, Robert Rietty as Alexander III and Edward Woodward as Clement are all other examples.
- One-Scene Wonder: John Gielgud as King Louis of France, Sian Phillips as Gwendolyn.
- Retroactive Recognition: Edward Woodward has a minor role as a French courtier.
YMMV / Becket
