Rock and roll band Def Leppard explain why they wanted to make a film about their concert Viva Hysteria.
The film was shot in Las Vegas earlier this year and it was the first time they had played any of their records from beginning to end.
Front man Joe Elliot and Rick Savage maintained they have been asked to do it for a number of years and were not 'jumping on any bandwagons'.
