Looks like Hobbit director Guillermo del Toro will follow the example of fellow filmmakers M. Night Shyamalan and Alfred Hitchcock by putting himself into his own movies. (Director Peter Jackson also had small parts in The Lord of the Rings.)
Del Toro posted on the message boards of TheOneRing.net that he will make a cameo appearance as a small monster:
"I had a hand on the design of the creature and I will personally sculpt the appliances that will be applied on my face and hands. I used to sculpt the creatures for NECROPIA (my FX company) and I miss it a bit. I will have a line or two and die quickly."
Del Toro didn't say much more about his brief role in the two movies based on J.R.R. Tolkien's book, the predecessor to The Lord of the Rings. The Hobbit is in preproduction in New Zealand.
