The My Little Pony movie has been bumped up from it's original November release date to a new, one month earlier date of October 6, 2017. According to Deadline, this puts it in competition with an untitled Warner Bros film, and another one of those Marvel movies.
I don't think this will change too much on the production side, but it's definitely the first time we have ever seen a deadline on pony bumped. Consider me surprised and more than alright with it!
Thanks to Joshua, Jason, Scortex, and everyone else for the heads up!
