Jeff Wayne's rock music version of HG Wells's 1898 novel brought together at the O2 arena in Greenwich a giant widescreen, a 45-piece orchestra energetically conducted by Wayne, five on-stage actors and Liam Neeson as narrator in holograph form (a novel way to telephone in a performance). It was filmed there last December, and the resultant documentary record may be a useful aide-memoire to those who saw it but it's not much of a film.
