Question: How did the alien egg get on board the Sulaco? I thought it was by the Queen but she did not have that organ that she was connected to when we first see her and so she couldn't reproduce eggs.
Question: Why didn't James Cameron return to direct? I know he made more than a name for himself after Aliens but I don't understand why the studio wouldn't ask him to return due to how good Aliens was. And why was a debut director (David Fincher) brought in with such a high budget? Wouldn't the producers think of choosing a more experienced filmmaker to deal with the budget and actors, considering how strong the previous films were?
Question: In the infirmary, when the Alien gets close to Ripley, and then (we realise why later in the movie) pulls back and leaves her, because she is carrying the queen chestburster, why doesn't the Alien hold her, take her with him, into the vent system and cocoon her like we see the others do to all those other humans in Aliens? It seems to be remiss of the creature to let her run around, as opposed to guarding her, especially since it seems to be a "guard."
Question: Why is the animal host switched out between the theatre release and the DVD release? Does this switch have any major differences between the two versions? I've only ever seen the theatre version.
Question: I know that an regular alien comes from a face-hugger, but how do they make a queen alien?
Question: Towards the end of the film after Ripley refuses to give herself up and tells "No" to Bishop and closes the gate, Bishop and the men in white go back down the stairs. As we cut to the long shot, we see one of the men in white running up to the metal fence and grabbing hold of it as though he is trying to climb over it carrying what appears to be a shoulder mounted camcorder. He is not part of the production crew because he is wearing the same costume as the other actors, but this is not dwelled upon so it seems like a pointless prop. Was this to add a similar feel to the previous films of recording footage on the planets?
Question: How did the ox (or dog) get the alien inside of it? Did it get facehugged or something? If so, how did the facehugger survive the escape pod and come to land?
Question: How did Newt die?
