Elizabeth Taylor has no line.
For the secondary roles, director Richard Burton, an Oxford graduate, cast drama students from Oxford University.
The Pageant of the Seven Deadly Sins does not use the dialogue from the original scene. Instead, Burton used passages from Marlowe's other plays: _Edward II_ (for Lechery), _Jew of Malta_ (for Avarice), and _Tamburlaine the Great Part One_ (Pride). Two of the Sins, Gluttony and Sloth, do not appear in the film at all.
