I’m standing in a cinema foyer waiting excitedly to be allowed entry. I’m here with two of my oldest friends, both male, whom I’ve known since I was a kid. We’re surrounded by similar thirtysomething males, a few women and huge hoardings depicting characters from the film we’re about to watch. This is the British Film Institute’s IMAX Cinema, located in the South Bank district of London. We’re here to see Tron: Legacy, the sequel to a film that meant a lot to us in our youth, Disney’s 1982 movie Tron, about a character who is sucked into a computer game world.
