The Summer 2011 issue of Studio CinéLive contained a HUGE feature on the Harry Potter series. The issue also included some new behind the scenes shots from Harry Potter and the Deathly Hallows: Part II.  The issue has a section for each film, as well as additional articles on Emma, Dan, The Theme Park, Alexandre Desplat (the composer for the last 2 soundtracks) and more! You can see the photos in the gallery!
[There is actually a pdf download of the issue available, I won’t post the link, but you can find it with google]

Thanks to SS for the initial tip, the cover of the issue as well as an additional photo were found by me.
