Geez, poor Sybill Trelawney has the crappiest luck. First, Dolores Umbridge goes after the zany teacher and tries to get rid of her, and then we learn that she's been written out of the next installment, even though she plays an important part in Harry Potter and the Half-Blood Prince. And now, well, now we don't even get to look forward to her in the final double installment. No big-screen goodbye for us, unless Order of the Phoenix heads back to theaters. (This is assuming the Harry Powers That Be don't recast her for the final film.)
Emma Thompson has told MTV that she's given up the Harry Potter world to make another Nanny McPhee film. It makes sense -- she wrote and starred in the first, so naturally it "means much more" to her. So, while she won't be magical with Harry, Hermione, and Ron, she will delight in magic with the tentatively titled Nanny McPhee and The Big Bang. This time around, it's one hundred years after the first film, and focuses on "The big war, and a war between these two sets of extremely different children."
I can't help but wonder -- is this why she wasn't in Half-Blood Prince too?
