A new documentary about Madonna gives fans an insight into the mixture of hard work and spirituality which drives the singer - but despite its title, there are few fresh revelations for fans.
"I'm Going to Tell You a Secret," which will be screened on [British network] Channel 4 next month, follows her 2004 tour from the dancer audition stage through to the final performance. The two-hour film is directed by arty pop video director Jonas Akerlund and executive produced by the singer herself, more than 20 years after her first hit. Chris Leggett reports.
