In case you didn't know before, see They Shall Not Grow Old.

Watched it today, it's absolutely fantastic. The colorization and 3D are both impressive, and Peter Jackson has made a compelling film about World War I. "But wait," I hear you say, "It's only in U.S. theaters for two days and today was the last day to see it!" Fear not, there is still hope. In January and February, Warner Bros is going to release it in a limited amount of theaters as a regular run. That means you can still see it on the big screen! So do it then! You won't regret it. via /r/movies http://bit.ly/2Q9joc9
