I've got this from the empire website.
Winslet For Potter?
Kate rumoured for Fleur Delacour
23 March 2004
Now we’re not sure that we believe this, but The Mirror exclusively reported this morning that Kate Winslet has been talking to producers of Harry Potter and the Goblet of Fire. She has apparently been offered “an important role as a young French wizard or something like that” – which would make her Fleur Delacour, Harry’s opponent in the Triwizard tournament.
The story was based on a quote from Winslet’s husband, director Sam Mendes, who said that Kate had met with producers and was still considering the offer. He apparently urged her to take the part for the sake of her children, Mia and Joe, who might never forgive their mother for turning down a part in the kid lit juggernaut. The producers of the Harry Potter films, in fact, have kiddie power to thank for most members of their stellar cast, who came under intense pressure from children and grandchildren to accept even small roles.
Although “an important role as a young French wizard” would mean that Kate was set for Fleur, we can’t help thinking that, at 29, she is possibly not the most likely choice for a 17-year-old French girl. Assuming that the rumours of Harry Potter talks are true, she might equally be in line for the role of Madame Maxine, the French headmistress, or another role completely. We will keep you up to date with more news as it emerges. Filming on The Goblet of Fire began yesterday in Scotland, but the cast will not be on set for some time yet.
