CJ CGV, South Korea's largest theater chain, debuted a new theater projection format last week at the country's Busan Film Festival. Dubbed ScreenX, the ultra-widescreen format encompasses 270 degrees of view projected with three cameras. But unlike Hollywood's Cinerama (which had a 150 degree field of view), ScreenX isn't projected on one curved screen. It's a composite of the primary screen and two other ones on the left and right walls. Director Kim Jee-woon (I Saw the Devil, The Last Stand) was hired to direct a 30 minute action short on the format, using a special rig made up of three RED cameras. CJ CGV has already converted two dozen theaters to accommodate ScreenX, a process it says costs around $150,000. Watch an AFP clip demoing the new format below.
