Giancarlo Giannini (born 1 August 1942) is an Italian actor and dubber.

Giancarlo Gianini as René Mathis.

Giannini was born La Spezia, Liguria, Italy. He studied at the Accademia Nazionale d’Arte Drammatica in Rome, and made his film debut in a small part in Fango sulla metropoli in 1965.

In 1976, he starred in Seven Beauties, for which he was nominated for the Academy Award for Best Actor, which is unusual in that his performance was given entirely in Italian. He dubbed Jack Nicholson’s voice in the Italian release of both The Shining and Batman; he is the official Italian dubber of Al Pacino. His fluency in English has brought him a number of featured roles in Hollywood productions, most notably as Inspector Pazzi in Hannibal. He has also appeared in A Walk in the Clouds and Man on Fire.

Perhaps his best-known recent role is as French agent René Mathis in the James Bond films, Casino Royale and the sequel, Quantum of Solace.
