PLEASE TAKE THIS WITH A MASSIVE AMOUNT OF SALT!!!!

UPDATE

Apparently this is coming from people who were actually working on production on the Fantastic Four reboot. Basically, Josh Trank came into production high as hell, messed up a ton of the set pieces (which are worth hundreds of thousands of dollars) to the point where Fox had to publicly apologize to the cast, crew, & people who they worked with for the set pieces. These guys are also saying that Josh Trank is basically screwed in both this movie & is most likely getting booted from Star Wars. Supposedly this was why Marvel is distancing themselves from the Fantastic Four brand (cutting off merchandise, canceling the comic, blowing up the reboot cast in Punisher, etc.) seeing as they hated what was going on behind the scenes. This would also explain why the cast has kept quiet about the movie as of recently, & it would explain the delay. The people on the set are saying that don't be surprised if the movie doesn't come out at all. Again, take this with a grain of salt & I'll get more links as this story develops, but the video I'm linking (or more specifically Armin) does have sources within Holywood (he got access to an early draft of the Sinister Six script & did a video on it, separate from the SonyGate leaks).
