Actress Sienna Miller has shared her thoughts on what makes a true Casanova ahead of the world premiere of Lasse Hallstrom's new comedy at the Venice Film Festival.
Sienna Miller's love life has made her a tabloid favourite
"Casanova is an intriguing character, he's magnetic. And I think that's what women are drawn to.
"Women are interested in men, men are interested in women - Casanovas or not Casanovas," said Miller, whose on-off romance with actor Jude Law has been the subject of much recent tabloid speculation following his dalliance with his children's nanny.
"Personally I've met a few Casanovas that I've liked, and a few that I haven't," added the 23-year-old actress, still noticeably without her engagement ring.
"And I hope to meet a few more," she added, enigmatically.
Miller, who shot the film in Venice over a period of four months, agreed it was a very romantic city, but declined to respond to suggestions that she might get married there.
She applauded the role of Francesca "an early feminist" and the woman who finally captures the heart of Ledger's Venetian libertine.
'Refuses to be seduced'
"She's a strong, independent woman among these flirtatious, silly women - she holds firm to what she believes in and refuses to be seduced."
"Casanova is charming, charismatic and beautiful, but the appeal for Francesca was actually that he sacrificed himself for her, that's the moment she falls in love with him."
The film's stars arrived in style
"It's more about self-sacrifice and less about his charms, and what other women are drawn to," said Miller.
Of her co-star Heath Ledger she said: "Heath has enough seductive ability naturally, he didn't need any tips from me."
For his part, Ledger - whose girlfriend, actress Michelle Williams - is expecting their first baby - said he could not compare himself to the legendary Italian lover.
"I certainly have an appreciation for love - and Casanova was a man who really fell in love with each woman or man, as opposed to Don Juan who woke up the next day and laughed in their faces.
"I too have that appreciation for love - just not so many women!"
Certainly the colourful shoot in Venice proved a welcome break after the intensity of Ang Lee's Brokeback Mountain, in which Ledger plays a gay cowboy in 1960s America.
"Brokeback Mountain was such an excruciating shoot, torturous at times and I went straight from that shoot to this. So this really became a working holiday. It was such a wonderfully relaxing environment that Lasse built for us."
Lasse Hallstrom was keen to make the film fun to work on
Director Hallstrom shared Ledger's delight in the film-making process, but the director admitted to taking "lots of liberties" with the historical facts.
"I haven't done a comedy since my TV days in Sweden, so this was like going back to my roots," said the director of The Cider House Rules and Chocolat.
"The real Casanova is wonderful idea for another movie - I'd love to make that one too."
