I have to say... i detest Jeremy Irons in fantasy themed films. Dungeons & Dragons and Eragon for instance... he is ghastly in both. No matter how bad a director or script, an actor of Irons supposed talent should be able to still perform... he fails miserably in both - indeed in DnD he was upstaged by Marlon Wayans of all people, and then in Eragon by a CG dragon with Rachel Weisz's voice...
Also, The Rock... he seems far to bulky to play a horseman. Khal Drogo may be huge, but my image of him is more rangy with long arms and legs, strong yes, dangerous looking yes, but not bulky... thats not the type of warrior the Dothraki are... also, i saw them being of more mongol appearance (obviously just bigger), the Rock's polynesian features are almost right... shame about the overly massive musculature..
