OSGH is the only cinema in Shanghai that has a Star MAX theater, which uses a hybrid of technologies from Dolby Laboratories, Sony, Klipsch, Tsinghua University’s School of Architecture and many others. It has a giant curved screen and uses Dolby surround sound. The screen at OSGH’s theater #6 is 20m wide and 8.5m tall. The theater intends to make you feel as if you are watching the film in a galaxy — the “stars” will be twinkling during the entire film, which might distract some people. OSGH also has an MX4D theater. Compared with the more common 4DX, MX4D theater seats have a much stronger and faster “rollercoaster” effect, but other differences are less distinct.
