so ok... i distinctly remember they said the start date is late summer of this year... then in the next interview they said, later this year..... and now its there is no start date?

ok sounds like the script is a bit uhoh maybe they should get Steve Kloves to help out again? cant blame JKR if she's having some trouble with a screenplay, this is her first time out, and any writer can tell you that writing screenplays and novels are two very different beasts.
