FORMER ITALIAN LEADER SILVIO BERLUSCONI'S SEX LIFE TO BE IN A PORN MOVIE.

ITALIAN soft porn director Tinto Brass, the subject of a documentary screening at Venice film festival, says he wants to make a film about ex-premier Silvio Berlusconi's escorts.

"I want to make a film about Berlusconi. I had in mind the title 'Thank you, Daddy'", Brass said, referring to the nickname given to Berlusconi by the girls who attended the famously bawdy parties in his villa.

Brass - best known for his erotic films All Ladies Do It, a raunchy take on Mozart's opera Cosi Fan Tutte, and the brutal cult movie Caligula - is in Venice to mark the screening of "Intintobrass", a documentary about his life.

Kicking back on the terrace of the luxury Excelsior hotel with his busty companion Caterina Varzi, who he describes as his "muse", the 80-year-old lamented "the preference today for senseless internet porn over crafted erotic films."

His would-be subject matter, the 76-year-old Berlusconi - who denies frequenting escorts or hosting lascivious parties - was found guilty in June of buying sex from a then 17-year-old prostitute nicknamed "Ruby the Heart Stealer".

The self-proclaimed playboy features in a separate fictional film showing in Venice, Portuguese director Miguel Gomes's ironic Redemption.

Berlusconi has been married twice.

His second wife, Veronica Lario, filed for divorce in 2009, describing Berlusconi as "a dragon to whom young virgins offer themselves" and saying she could not stay with a man "who frequents minors".
