there be no esperanto in this moviei watch this movie specifically because imdb list esperanto a one of the language use . but imdb be mistake about the language use in this film . there be absolutely no esperanto at all . it almost all english with a couple of word of navajo . do not watch this film if youre look for esperanto movie . other option instead be idiot delight ( with clark gable ) which have a bit of esperanto and incubus be all esperanto ( although completely mispronounce ) and and there be some esperanto street sign in charlie chaplin the great dictator . there be suppose to be some spoken esperanto in gattaca a well and but i never hear any . aside from that and the other reviewer be right . this movie be a complete mess . spend your time elsewhere .
