As for the celtic not being mentionned in tha book, the answer is simple, Mcfarlane brought that name up. "Celtic" PA never mentionned it anywhere. None that I recall. But in tha book, they talk about a arroguant pred that is bit older. Could be the Celtic. Anyway, I think that we should see the predbusta at the end too. Someone mentionned that earlier, that would be cool not to see the predalien in this movie, but in tha sequel. Would give time to PA to make a real good predalien. If he is back for tha sequel if they are a sequel. Anyway, I hope that the queen will fight harder than that in tha movie. Cuz it almost look easy for them to get rid of tha queen. And lex jumping on her stabing her. man where do ya want her to jump? like if she does so, the queen could empale her with her tail. Anyway, I will trust PA on this to make the fight damn nail bitting. I want some action. SPOILERS!!!! Even if tha queen in tha book take care of another pred back in tha pyramid, wich I think was the celtic, Althoug, I would love to see her fighting the elder instead of tha lex and scar combination. Or the 3 at a time. so that way it could be more equivalent. Cuz a human with a spear + a pred with disc and spear, not good. But an elder in would be better, or more action. Anyway well see.
