Filmmaker JAMES CAMERON and effects master STAN WINSTON have resigned from the board of directors of the Venice, California-based effects studio they co-founded five years ago, DIGITAL DOMAIN. They will retain their financial stakes in the company. A Digital Domain spokesperson said the resignations were an administrative move to avoid conflicts of interest for the two former board members who have exclusive deals with studios. . . . Digital Domains vice president-creative director PRICE PETHEL recently left to take on the same position at DREAM QUEST IMAGES, Disneys effects division. . . . Santa Monica, California-based POP TELEVISION has hired visual effects supervisor ALEX FRISCH, visual effects artist CHRIS STAVES, visual effects producer NESYA HORSBURGH and director of technology ANDREAS WACKER, all formerly of neighboring studio 525 Post, with the intent to launch a new, internal visual effects boutique. . . .
