They at least had better not join the Wilhelm Scream trendy bandwagon here-yes I am sure it will show up in both of the Hobbit films (as it did in all 3 LOTR movies-thank you PJ), temporarily upsetting my willing sense of disbelief in the process.
That’s not quite right, I think. It will be largely about the antecedent to the Alien xenomorph - an earlier stage of its development.
