HBO's "Harry Potter" television adaptation is slowly coming together, but we're still a ways out from actually getting it on our screens. That said, we are learning more and more as the months go on.

The show has started production at Warner Bros. Studios Leavesden in the U.K., which is where the original movie franchise was filmed from 2000 to 2010. The network has also made a few more casting announcements for supporting characters, including Harry's cousin Dudley Dursley and fellow Gryffindor Neville Longbottom.
