According to Inquistr on Aug. 18, Bryan Singer tweeted what appears to be a photo of their last day of shooting of "X-Men: Days of Future Past". It looks as if Singer believes there is a well deserved celebration in order.
“Just wrapped! Eternal thanks to our amazing Montreal crew! See you at the party".
It may take a brief moment to decipher Singer's text speak, but from the picture and the comment, they seem to be well satisfied. Even though this may have been the final tweeted picture of the filming, Singer will probably still keep fans up to date with post-production content. The project continues forward in earnest with a lot of work to do.
Fans even got an opportunity to see a leaked trailer of "X-Men: Days of Future Past" that was filmed with a smart phone, but Twentieth Century Fox made sure every piece of said leaked content was removed from the internet.
That being said, it would probably behoove those just to see the movie in full quality when "X-Men-Days of Future Past" is released May 23, 2014.
