a others have note and jason robards performance a brutus have real problem and particularly at the start . while play the character a vague and distract be certainly justify by the text and robards often appear just this side of comatose . james mason be far well in the old film version . the big and best surprise be heston strength a antony . he believably convey an interesting mixture of loyalty and craftiness and and ambition . and his work in the funeral oration be well pace and well direct . overall and this version have a lot go for it it among the good shakespeare adaptation that i know of .
