Australian special effects company Rising Sun Pictures worked on several scenes for
Harry Potter and the Order of the Phoenix, including the fireworks, Grimmauld Place, Hedwig, and Harry being possessed by Voldemort.
Quote:
To show Voldemort’s eyes and sockets appearing on Harry’s face, the team used three distinct elements within Shake: an iris/pupil treatment morphing Harry’s wide pupils to match Voldemort’s small pin-hole pupils; an iris color change; the darkening of Harry’s eye sockets, using three different mattes that were tracked into position.
