We now know that filming of X-Men: Days of Future Past will begin shooting next April for its July 18th, 2014 release, but director Bryan Singer (who has recently joined Twitter as @BryanSinger) is now Tweeting details about the production. It's hard to say exactly how long this will continue for, but it's well worth following the filmmaker on the off chance that he reveals some particularly juicy details. Don't forget that it was Singer who actually revealed the title, so fingers crossed! Judging from the Tweets below, the sequel is set to be filmed at least partially in Montreal, Canada. X-Men: First Class was shot primarily in Matthew Vaughn's home country of England, but Singer did both X-Men and X-2 in Toronto and Vancouver so it makes sense that he will return there.
