when you combine robert deniro our great actor and billy crystal one of our great comedians how can you go wrong . it be a joy to see the two great on screen together . they be absolutely magnificent and have incredible chemistry . the way their personality conflict with one another be a riot . another noteworthy member in the cast be joe viterelli and who also a riot a deniro henchman jelly . lisa kudrow have some funny moment and chazz palminteri be . chazz . he such a cool actor that his mere appearance can make a film worthwhile . he only have a supporting role and but he great a always . the film have some priceless gag . some of the best line i have ever hear be from this movie . one that really stick out be when deniro consults crystal in the middle of the night because he couldn not . get it up . yes and it what youre thinking . when crystal advise him to take some sort of drug to help his problem and deniro reply drug i do not take drug . a hard on should be get legitimately or not be get at all . crystal reply in a dry sarcastic tone and i think mark twain say that . i also have to note the hilarious scene where the two guy come face to face for the first time and in crystal office . deniro ask the shrink representdo you know me . yes and he reply . no you do not . no and i do not . do you see my picture in the paper . yes . no you do not . no and i do not . and there a great interaction in which crystal explain a theory by sigmund freud about a child in greece who kill his father because he want to marry his mother . deniro quickly reply representare you say i wan na fk my mother . have you see my mother . well and freud say well and freud a sick fk . there so many memorable moment and but i do not want to give them all away to those who haven not see the movie . because these be some of the funny gag in film history . one moment and this will be the last one i will mention that also make me roll with laughter be the funeral sequence in which a family member get a little over affectionate with crystal . deniro reply and him i do not know . when i saw at in theater and the place be fill up and people would laugh out loud in unison like a fifty sitcom audience at every funny scene . that a rare occurrence and and i feel great joy whenever it actually happen . the comedy be not do in blatant and screwball fashion . the actor let the laugh come to them and and play it straight . crystal have a magic way of deliver sarcastic dialogue that only people like albert brook and woody allen can surpass . deniro spoofs his gangster persona without be superficial about it . he let the audience search for the inside joke on their own . people say deniro be not suit for comedy . sure and he not the jim carrey type of comic actor and but i think that what make it work . in film like this and meet the parent deniro doesn not try too hard and be never over the top . he express the comic dialogue with good timing and good delivery and without make it look like he try to be funny . and joe viterelli and who be in other movie but i first discover him on this one and be great at play the bumbling henchman and i hope to see him more often . he have great talent . analyze this be a hilarious and wildly original comedy that should have you roll in the aisle . this be one comedy that would not make you leave with guilt . youre watch two great performer and the humor and though sometimes racy and be all in good taste . my score represent 8 ( out of 10 ) .
