Perhaps so you can have red eyes if you're an orc, who knows. ThreeFootSix don't need to know if you can tapdance while playing the banjo. Swordfighting and horseriding are assets, and some people brought along photos of their horses. Somebody told me their friend had sold their hedgerows to the film company, who've dug them up whole and replanted them around the Hobbiton set. Another neighbour was very admiring of the earthworks that Mr. Alexander was getting done for nothing.
Earthworks can be a big expense for farmers.
Eventually it was our turn to be measured and have our photo taken, and then it was all over. Afterwards some people said they could see that on their application form they'd been marked down for some particular type, orc or hobbit. We hung round and saw a woman don a rubber head and shoulders mask and wave some sort of club or sword around for the benefit of the photographer. I've got no opinion, it could have been a Halloween mask from The Warehouse for all I knew. Nasty sallow snubnosed thing it was, but presumably such things are painted later.
