3. Nicolas Cage – Captain Corelli’s Mandolin (2001)

After a decades-spanning career of semi-consistent lunacy, the only thing audiences have come to expect from Cage is the unexpected. However, his Italian accent in 2001 war drama Captain Corelli’s Mandolin is cartoonish and borderline offensive.

Complete with hilariously over-the-top inflection, Cage’s accent is practically incomprehensible, and it sticks out like a sore thumb next to the fairly believable accents of co-stars Penelope Cruz and John Hurt.

Still, to Cage’s credit, he was set up to fail by the decision to have the film’s Italian characters played by English speaking actors. Still, Cage is famously part of the Italian-American Coppola family, so you’d be forgiven for thinking that he might have brought a little authenticity to the role. Instead, the otherwise serious film plays out with Cage’s caricature of an accent ringing through practically every scene, which plays havoc with the film’s tone.
