The ides of March
British wit: in the opening scene George William Mawwell (Michael Hordern) shortly before being killed is reading The Financial Times of March 15, 1972: the ides of March, the day Julius Caesar was assassinated in 44 B.C.! The date is also in his tombstone during his burial
As for Edward Kendal Sheridan Lionheart (Vincent Price), in spite of having been warned about it when I suddenly saw him with that effeminate attitude and wearing that afro I almost spat up what I was drinking!!
