According to an MTV blog report, Emma Thompson will not reprise the role of Professor Trelawney in the two-part Potter finale. Forced to choose between Deathly Hallows and the sequel to Nanny McPhee, Thompson said the choice was obvious.
“The Harry Potters are great big franchises that are something I’m not emotionally attached to or necessarily particularly creatively attached to. That’s more like doing a turn, whereas the Nanny McPhees are something I’ve written. The art is in those films, they’re very handmade, they’re something that’s very close to me. Those are the ones I really care about.”
