In the interviews and behind the scenes videos here, we learn how Jackson and his team solved the film speed problem to make the old reels look natural, how they created a color palette and removed blurriness and blemishes.

The videos in this piece show the amazing amount of work that went into creating “They Shall Not Grow Old”.
