That photo's from the 2015 San Diego Comic Con, one of the largest gathering of Fox's Marvel movie actors in one place. Fantastic Four was coming out in a couple of weeks, Channing Tatum had just been confirmed for Gambit, and Deadpool and Apocalypse were coming out the next year.
Why will this not be cancelled when Corman 1994 Fanatstic Four movie which is also based on Marvel got cancelled?
It won't be cancelled because they're literally in the middle of promoting it's release. The time for cancelling it would have been mid-production or, at the very latest, before re-shoots. It's very clear from the activity on the movie that it's gonna be released.
I can't believe they haven't made any official announcement. Which makes me think that photo might not mean much. At least come out and say that this is the date for trailer release. What you gotta loose?
