While the official Twitter account for X-Men: Days of Future Past has been releasing numerous character photos over the past few days, director Bryan Singer is posting his own behind-the-scenes photos during the post-production process. The director shared a new look at a Sentinel on his personal Twitter account today, announcing that he has wrapped on pick-up shots in Montreal. The cast and crew headed back to Montreal for reshoots in November, but those were only supposed to last a few weeks before Christmas.
