Spice World (1997)

The Spice Girls zip around London in a double-decker tour bus in a film that is less a story than a celebration of the band at its peak, released for Christmas 1997. It is silly, proudly ramshackle and not good cinema by any normal measure, and even fans watch it with a grin rather than a straight face. It earns its place as a time capsule. No other film catches Girl Power at its height so shamelessly, or shows so clearly how big British pop had become in those years. Watch it with people who remember buying the singles.
