8. Heath Ledger and 'The Dark Knight'
2008 saw promising young actor Heath Ledger die of an accidental overdose aged 28, just as Christopher Nolan's epic Batman adventure 'The Dark Knight' entered post production. The incident happened while Leger was also midway through filming Terry Gilliam's 'The Imaginarium of Doctor Parnassus'.
When 'The Dark Knight' opened, it became one of the biggest box office and critical smashes of all time. Ledger's performance as The Joker was tipped as Oscar worthy making 'The Dark Knight' a triumphant coda to a tragically brief but illuminatingly diverse career.'
