The genus Manta is part of the eagle ray family Myliobatidae, where it is grouped in the subfamily Mobulinae along with the Mobula devil rays. In 2017, an analysis of DNA--and, to a lesser degree, morphology--found that Mobula was paraphyletic with respect to the manta rays, and they recommended treating Manta as a junior synonym of Mobula.

She was later replaced by Anne Hathaway, a classically trained soprano, in 2004. However, Hathaway dropped out of the role because the production schedule of the film overlapped with The Princess Diaries 2: Royal Engagement, which she was contractually obligated to make. Hathaway was then replaced with Emmy Rossum. The actress modeled the relationship between the Phantom and Christine after Suzanne Farrell and George Balanchine. Patrick Wilson was cast as Raoul based on his previous Broadway theatre career. For the role of Carlotta, Minnie Driver devised an over-the-top, camp performance as the egotistical prima donna. Despite also lacking singing experience, Ciarán Hinds was cast by Schumacher as Richard Firmin; the two had previously worked together on Veronica Guerin. Ramin Karimloo also briefly appears as the portrait of Gustave Daaé, Christine's father. Karimloo later played the Phantom as well as the role of Raoul on London's West End.

The projector is either a Texas Instruments Digital Light Processing device or Sony's reflective LCOS (liquid crystal on silicon). A push-pull electro-optical liquid crystal modulator called a ZScreen is placed immediately in front of the projector lens to alternately polarize each frame. It circularly polarizes the frames clockwise for the right eye and counter-clockwise for the left eye. The audience wears circularly polarized glasses that have oppositely polarized lenses that ensures each eye sees only its designated frame. In RealD Cinema, each frame is projected three times to reduce flicker, a system called triple flash. The source video is usually produced at 24 frames per second per eye (total 48 frames/s), which may result in subtle ghosting and stuttering on horizontal camera movements. A silver screen is used to maintain the light polarization upon reflection and to reduce reflection loss to counter some of the significant light loss due to polarization filter absorption. The result is a 3D picture that seems to extend behind and in front of the screen itself.
