And it showed. Oh boy did it show.

But that doesn't mean that all of the human suffering was inflicted upon the audience. The actors endured their parts, too. Midway through the second movie, The Desolation Of Smaug, our heroes need to get into Laketown to proceed. So a friendly human stuffs the 12 dwarves and one hobbit into barrels filled with fish to smuggle them in.
According to one of the actors, filming this scene left every actor who appeared in it covered in "fish juice." Absolutely everything was soaked in the nasty slurry -- their hair, clothes, prosthetics, any open orifices, everything. Moreover, in a hilarious twist of fate, one of the actors (Adam Brown; no relation) apparently had a massive "fish phobia," and while he managed to get through filming the scene, he had to be rescued by Andy Serkis afterwards. Serkis has played a lot of thankless roles in his time -- Gollum, Caesar the ape, Supreme Leader Snoke -- but his greatest part? Rotten fish hero.
