After I was persuaded to come out from under the table where I had, erm, fallen, I found out this massive hulk of hair and teeth was just an actor.
It was Lawrence Makoare, who played Lurtz, head of the Uruk-Hai in Fellowship of the Ring.
He was there to help open the Lord of the Rings Motion Picture Trilogy Exhibition at the Science Museum in London.
His make-up was awesome. He looked like a real orc - not that I know many real orcs.
I stopped being scared when, through a mouth-full of false fangs, he said, "Thish coshtume'sh really hot. Can I get a glassh of water?"
I felt pretty sorry for the New Zealand actor - when he was making the film, he had to be in make-up at ten at night to start filming at five the next morning!
