Alien inner mouth is too long, Predators dreadlocks are too long, Predators upper teeth are in pair normally (snake reference) but in this movie they have more upper teeth, I dont like these changes, but in this film. . I respected that as something different made for totally different (lore) dimension. The entire movie was filmed in my country (Czech Republic) thats the reason why they created so much with such a low budget, we arent that expensive. Paul Anderson is horrible director, so this movie could be even worst thanks to him. My dream is to see one day an Alien or Predator film from someone like Steven Spielberg, Peter Jackson or once again from James Cameron, damn. . I will be highly interested in the Predator from James Cameron perspective, of course if he ever will have any interested in it.
