Festival chairman and producer Mark Canton and festival director Pascal Vicedomini made the announcement today [December 18].
Luhrmann and Jackson will attend screenings of their latest projects - Australia and The Spirit, respectively.
'As with his current film Australia, Baz Lurhmann continues to carve out his own unique path in the film industry, making visually stunning and epic productions,' Canton said. 'Samuel L Jackson has become one of Hollywood's greatest actors, giving knockout performances with every new role.'
'We are honoured to have these two great talents at Capri, Hollywood - a fitting addition to our top tier international attendees,' Vicedomini added.
The festival will run from December 26-January 2.
