VENICE, Italy - As the star of three films at the 62nd Venice Film Festival, it might be called a Heath Ledger Festival but the Aussie actor said he was in ``a slight state of denial.''

``It's an honor and it's exciting but I'm exhausted from promoting each one. You know I'm pretending I just have one common picture,'' said Ledger, whose gay cowboy romance, ``Brokeback Mountain'' with Jake Gyllenhaal, world premiered Friday, followed by yesterday's world premiere of the made-in-Venice comedy about thelegendary lover, ``Casanova.'' Co-starring is Jude Law's ex-fiancee Sienna Miller. Tonight, ``The Brothers Grimm'' with Matt Damon and Ledger has its European premiere.

Ledger's Casanova is anything but historical. ``We're making a romp and it's just to enjoy,'' he said of playing a swashbuckling lover pursued by the Inquisition for his immoral ways who falls for the spunky Miller, a woman who resists an arranged marriage and secretly publishes proto-feminist books under a man's name. The picture won't open in the United States until December.

Questions about Casanova had a personal impact for Miller since it's now obvious she was engaged to one. She no longer sports Law's mega-carat engagement ring after his affair with his children's nanny became an international scandal and seemed to put a nail in the coffin on any notion of reconciliation.

Asked if she thought Venice, where everyone spent four months last fall filming ``Casanova,'' was a romantic place she would return to for her wedding, the blond Brit smiled. ``I agree it is one of the most beautiful and romantic cities in the world and I look forward to coming back the rest of my life. And I don't know about getting married,'' she added.

When asked what's so appealing about Casanovas, Miller held steady. ``I think women are interested in men and men interested in women, Casanovas or not Casanovas. He's an intriguing character and I suppose women are drawn to that.Personally I've met a few Casanovas whom I've liked very much and a few I haven't. And I hope to meet a few more.''

Having laid Law to waste, or at least to the reject pile with that, she then smiled, gave a ``That's that'' look to her publicist and mimed shooting a pistol into her mouth.

It was Lena Olin, who plays Miller's randy mother in ``Casanova'' and was Jennifer Garner's on ``Alias,'' who had the last word on the power and not-so-lasting effect of a charming seducer like Casanova. ``The idea of seduction is very seductive itself, the thrill and the excitement it can bring to something that is not real love,'' Olin said. ``But if any woman has experienced real love, true love, that goes beyond all of that - and that becomes child's play.''

Then pointing to her husband, ``Casanova'' director Lasse Hallstrom, she crowed, ``I got that right here in my director.''

Following its world premiere, ``Casanova'' launched a black-tie opening night party on St. Mark's Square where, for the first time ever, a movie was allowed to film Carnivale sequences.
