Darb Designz has completed some finishing touches on his Jason X "Uber" mask. He was able to use a movie mold mask to get the details 100% on and the result is pretty amazing. It's not technically movie mold, but it's as good as a fan replica gets. You can get one at https://www.darbdesignz.com/store
One of the photos below shows a movie mold piece (the black one). The gray one is his unpainted prototype. Magnificent attention to detail.
