What is IMAX and why should you watch Oppenheimer on an IMAX 70mm screen?

Friday 21 July is a big day for cinema with the release of two highly anticipated but entirely different films; Greta Grwig’s Barbie featuring Margot Robbie and Ryan Gosling and, Christopher Nolan’s Oppenheimer with Cillian Murphy and Florence Pugh. Barbie may well be touted as the box office favorite – with projections to take roughly $110 million on its opening weekend (double what Oppenheimer is expecting). As camera enthusiasts, however, we can’t help but think the latter is a little more interesting. 

There are some key differences between Barbie and Oppenheimer other than the obvious (one is about plastic dolls and the other is about the development of nuclear weapons). While Barbie has been created in the standard 1.85:1 widescreen ratio making it perfect for almost every cinema screen in the world, Oppenheimer has been shot entirely on large format film and requires an Imax screen with a 1.43:1 aspect ratio if it is to be viewed as Nolan intended.
