i would not say this be a fact base film . with it many substories that probably do not happen but as far a dr. john harvey kellogg and the battle creek san be concern it be fairly accurate . dr. john harvey kellogg be pretty much a depict in this film and a most excellent job by anthony hopkins . however the real kellogg would make you eat half the yogurt and the other half be use a an enema . anthony hopkins and bridget fonda and matthew broderick and john cusack and dana carvey and michael lerner and colm meaney and john neville and lara flynn boyle and traci lind and camryn manheim all turn in great performance with hopkins and broderick and cusack and lara flynn boyle a stand out . i be not much for period base film but the amount of talent and the accurate detail of the quack medical device use make me change my mind and at least with this film . that say i do not like the film when i first saw it . it be one of my wifes video pick and while i have hear of the film i do not know much about it . it have just be release to video . the problem be that so many image of the film stuck in my mind . after see it several more time year later i fell in love with the film and it be in my top 20 film list . the film may be an acquired taste but chew and chew and chew and it will be good for you .
