Director Greg Beeman has a blog post
up that reveals some behind-the-scenes info relating to the Falling Skies season finale. The post contains spoilers so it's highly recommended that you watch the finale before reading the post.
Like previous posts by Beeman, this latest one sheds some light onto some of the various difficulties they go through in creating the show. For instance, the first hour of the finale, "Mutiny", was created as something called a "Bottle Show" which basically means it was on a more restricted budget to try and save up money for other episodes. Everything was going well with the episode until the final shot where Weaver rolls out with a squad to attack the aliens. For that scene the episode director, Holly Dale, really wanted to capture a specific look with the backdrop of the sun.
Unfortunately, some technical issues arose that caused them to miss the perfect moment. With it being a "Bottle Show", this normally would mean they'd just have to make do with a lesser shot, but Beeman fought for the scene and Holly was able to come back the next day and film it properly. They were able to make up money elsewhere in the end, but apparently it was a pretty close call.
Little stories like that really illustrate how much work goes into making just a single episode. As viewers, perhaps we sometimes take the end product we see on the screen for granted.
