much good than the early julius caesar and which star marlon brando a mark antony and james mason a brutus . in this version and jason robards a brutus be admittedly an embarrassment and but the rest of the cast be quite strong . the delivery of antony funeral oration by charlton heston be brilliant and powerful and well pace and the dramatic high point of the movie . richard johnson a cassius and john gielgud a caesar and robert vaughn a casca and diana rigg a portia be fine actor and with full dramatic presence and at home in shakespeare language . brief part and like the soothsayer and the cobbler and be memorably play . the screenplay omit two short passage that be important to the plot represent ( 1 ) cassius avowal in the first act and after his attempt to persuade brutus to oppose caesar and that if their position be reverse and he and cassius and stand as well with caesar a brutus do and and brutus make a comparable appeal to him and he would certainly not listen . ( 2 ) immediately after the assassination and a promise by brutus to antony servant of safe conduct for antony and who thus know when he come to the capitol and weeps over caesar body and challenge the conspirator to kill him also and that there be no danger of their do so .
