Australian actor Eric Bana is returning to his comedy roots to star in a new satire directed by Ricky Gervais.

The Hulk star will portray an arrogant New York radio journalist who decides to fake front line war reports from the comfort of his Manhattan home in a bid to save his struggling career.

British funnyman Gervais will write, direct, produce and co-star in Special Correspondents, a remake of the 2009 French release of the same name.

Bana initially rose to fame as a comedian in the early 1990s, appearing in sketch comedy series Full Frontal.
