I'm going to keep the post unlocked. When I first made the thread there was a lot of arguing, so I didn't want that to continue for a year or more without any news/rumors.
Also, I found another release date rumor on the net:
http://www.filmofilia.com/movie/twisted-metal/ This movie site has the release date set for Dec. 31st, 2013, but the fact is the project is still in pre-production, so that's a very unlikely date, but still, thought I'd share.
As for the lack of sources for the casting news, it may be stuff that is put on IMDbPro (so someone would see that and put it on wiki).
As for the director Brian Taylor, I wonder if he's currently working on writing the screenplay. He hasn't directed since 2011 or written since 2010, so he's had a lot of time to work on Twisted Metal. Also notable, TM will be the first movie he directs alone, which seems like it could be a lot of pressure for him, especially on a 7 figure budget.
Mosh, you just made me very excited again. I really hope they go through with the movie, and don't screw it up. Even if they made the movies like the Live Action cutscenes in the new Twisted Metal, I wouldn't be disappointed.
