ON first glance it looks as though age has not been kind to Nicolas Cage.

Sporting a bushy grey beard, complete with bedraggled hair extensions and glasses, the look was for his character in his latest film Army of One, which is being shot in Vancouver.

Based on a true story and written as a comedy, Army of One sees Cage play real life Osama bin Laden hunter Gary Faulkner (also known as the “Rocky Mountain Rambo”), a US construction worker who gave up his average ho hum life to pursue the world’s most hunted man.

Cage will star alongside Russell Brand in the film.

He’s not the only Hollywood star to devote himself to an extreme transformation, with some other celebs below showing their dedication to their craft.
