To date there have been several deviations made by Sideshow on their LOTR reincarnations. This version of the Wiki is just one of them. GTW PF is another one, and so is Frodo PF. I can say that by doing this, it makes it easier for me whether to buy the product. So far, all 3 have been easy passes. Even after having received the GTG LS bust, I'm still not sure if I made the right decision, because he looks to have a lot of makeup on him (paint app lousy???).
No matter how one tries to justify that this is movie accurate, ultimately, it's what the bulk of people's opinions are as to whether this is a passable representation. The consensus is that it's not.
