Sorry, it is a rumor - Tom Hanks dropped hints that they were working on TS4 in an interview back in June. The news kind of exploded after FN2 was announced. Both movies were trending on Twitter WW.
To those who are skeptical about this horrible shooting affecting box office: while not related much at all, this reminds me somewhat of those sniper shootings out east affecting the Red Dragon box office quite negatively.So disturbing.
So sad, sick, and senseless. I personally have no interest in seeing this movie right now, at least this weekend. 1. It just wouldn't feel right, 2. With the subject matter of the film I would just be too anxiety-ridden watching it.
