The Uffizi revealed that the Hollywood star’s visit lasted over two hours.
Franco admired every painting made by the Renaissance genius (1445-1510), including The Birth of Venus (c.1484) and The Spring (c.1482).
Franco was in Florence to present his latest film Hey Joe, a drama in which the actor plays a US Navy sailor stationed in post-World War II Naples.
In the movie, the protagonist falls in love with a young and poor local woman whom he is forced to leave, alone and pregnant, to go back to New Jersey.
When he eventually returns to Naples, he finds a changed city and significant challenges leading up to a stunning finale.
The movie is directed by Claudio Giovannesi, known for the Gomorrah TV series.
