the most overriding issue, for this critic at least, is the total lack of significant Middle Eastern and North African representation in the cast despite the very clear influence of MENA, Islamic and Arab culture on the desert planet and this universe in the original book and this film. I’ve written before about the importance of Fremen characters being played by MENA actors not least because their language is mostly made up of Arabic words, like “Mahdi'' (‘the rightly guided one”) and “Lisan al Gaib” (“the voice from the outer world”), respectively. Though it's notable that jihad, the phrase frequently used in the book, has now been replaced with "crusade" and "holy war".
