The UK fan page of 'Harry Potter' posted this:
We’re launching a new video treat called Magical Mondays today! Over the next seven weeks we’ll release an amazing piece of video content to brighten your day after the weekend. The first today is a great exclusive clip with Sugarscape showing Daniel Radcliffe learning Emma Watson mannerisms for the seven harrys scene, hit the Magical Monday tab to see it! http://on.fb.me/magicalmondays
Seems like 'The Quest for Hallows' failed. So that is why they looked for another interesting way to present their videos.
