We were previously informed that the movie will start shooting in April and now we seem to have a start date which was posted today at the myentertainmentworld website: DARK SHADOWS - April 11, 2011 - UK http://www.myentertainmentworld.com/mew/film_production_newlisting.html
A lot of the casting info discussed so far still seems to be speculative or at least not confirmed. It's hard to keep track of what is what. Perhaps someone could start a list of confirmed casting as it becomes known and add to it as more are revealed.
