The Science Museum’s IMAX Theatre is the only venue in Europe screening this blockbuster film in the IMAX 15/70mm format. Sequences expand vertically to give viewers a truly immersive experience, filling the entire screen and displaying 40% more of the image than can be seen in standard cinemas. We recommend booking early as demand is expected to be high.
