Spielberg dreams of becoming 'Indiana Jones'

'Indiana Jones' director Steven Spielberg is keen to trade places with Harrison Ford - because he has always fantasised about becoming an action hero.

Spielberg, 61, has directed four instalments of the smash-hit film series - returning to the set of the Ford action film for its latest instalment 'Indiana Jones and the Kingdom of the Crystal Skull', 19 years after 1989's 'The Last Crusade'.
