Ron Perlman (Hellboy) may be a great actor, but he’s an even better human being. When Perlman got word that Zachary, a six-year-old leukemia patient, told the Make-a-Wish Foundation that he wanted to “meet and become Hellboy,” the screen veteran was all in. Re-teaming with Spectral Motion, the effects company behind Guillermo del Toro’s Hellboy and its sequel, Perlman underwent the four-hour transformation process to become the comicbook demon and meet Zachary. Imagine Zachary’s surprise when he not only met Hellboy in the flesh, but got to become a pint-sized version of his hero, courtesy of the make-up and effects team. Hit the jump for more pictures from the event and more charitable work from Spectral Motion.
