for the major part assassination of trotsky move with a very slow pace and make the movie even bore from time to time . some scene be over dramatized and create an uneven tempo . richard burton represent character leon trotsky be minimize an old man walk around his villa speaking monologue and not enough to save the movie . alain delon act frank jacson and the assassin and with bad judgment . the character be overplay and not convince . you even have trouble hear what the man say when english not be his native tung . the story be very interesting and with burton in the lead one suspect that assassination of trotsky be a good film . sadly this be not the case and the movie can not be recommend . this be not a bad film but it suffer to much from an uneven tempo and bad direction and bad acting . it add up to negative .
