Finding out Italian actors with red hair is not easy, also because, especially with actresses, we can't always be sure whether their hair is natural or not.
However, here are two actresses who, if I'm not mistaken, are natural redheads.
Lucrezia Lante Della Rovere
She was born in 1966 in Rome as Donna Lucrezia Lante Montefeltro della Rovere. She is the daughter of Alessandro Lante della Rovere (1936–1995), who belonged to an ancient aristocratic family, and Marina Ripa Di Meana (1941–2018).
She made her debut in Mario Monicelli's Speriamo che sia femmina (1986) and performed in many stage productions, such as Quando eravamo repressi by Pino Quartullo, Risiko by Francesco Apolloni, Oleanna and Il cielo sopra il letto by Luca Barbareschi, Malamore by Concita De Gregorio, Borkman by Ibsen and Come tu mi vuoi by Luigi Pirandello.
She also acted in television dramas such as Orgoglio, Uno di noi, Donna Detective, Tutti pazzi per amore, Tutta la musica del cuore, La dama velata.
In 2005 she won the Taormina Film Festival for her role in the film Gli occhi dell'altro, in 2008 she won the Roma Fiction Fest for her role in the TV movie Ovunque tu sia, in 2012 she won Premio Flaiano for Malamore.
In 2008, della Rovere appeared in the James Bond film Quantum of Solace as Gemma, Rene Mathis' girlfriend.
She was born in 1941 in Gemona, province of Udine, and made her film debut at fifteen years old, in Alberto Lattuada's Guendalina. Very active in films and on television series, both in comedic and dramatic roles, from the late 1970s she gradually focused her activities on stage and in political activism, being a Partito Comunista Italiano deputy between 1980 and 1983.
During her career Gravina won a number of international awards, including the Best Actress Award for her performance in Alessandro Blasetti's Love and Chatter at the 1958 Locarno International Film Festival, the award for Best Supporting Actress for her role in Ettore Scola's La terrazza at the 1980 Cannes Film Festival, and the award for Best Actress for Margarethe von Trotta's The Long Silence at the 1993 Montreal World Film Festival.
