the actress says she has not been asked back to reprise her role as Fleur Delacour (aka Phlegm) for the sixth Harry Potter film. Indicating she has not read the final three books (including OotP which is now on DVD) and hopes to read them on her next vacation, she is quoted as saying:

Somebody already told me the end of ‘Order of the Phoenix,’ and I was like, ‘You’re ruining everything!’” Poésy laughed, since she plans to read the remaining books on her next vacation “back to back.” Still, she can’t resist asking for one one spoiler: “Has Harry done some bad things?”

She is uncertain if her character will be back as well for the film of Harry Potter and the Deathly Hallows
