You may want to do a trial run on some of the things discussed. IE, practice making the fire, gathering your dry tinder, getting that small pile started and then building it up to something you can use to boil the water necessary to make it safe.

One thing we discuss on this forum quite a bit is survival kits (do a search and you'll pull up lots of threads). These kits run from small pocket size Altoids tin kits to larger backpack size kits and are designed around the basic survival needs of fire, shelter, water and rescue/signaling. Before you start your survival trip you might want to make sure you each have a survival kit that addresses the Basic Needs of fire making (Bic lighter), shelter (large garbage bags) and something to carry, chemically treat or boil water. Short term survival doesn't need food, but the idea of a few energy/food bars (not candy) in a small kit is acceptible (my large kit has MREs). Other things that could be in a small kit are a fish hooks and line -- maybe you can catch a fish worthy of being dinner. Another thing to consider is that people in a survival situation want out. Rescue can be helped along with something like the signaling mirrors and whistles you also have in your kit. Many folks end up in a survival situation because they got lost; a compass to keep you walking in a straight line. Have you used a compass for woodland navigation?

Susan has a good point, few if any hikers who get lost are carrying an axe and .22 rifle, so while it may be fun and make chopping firewood easier, they aren't realistic. However, you should have a good folding knife on you or in your kit.

One thing you can build with that small knife and sticks you find is something like a figure 4 trap. Trapping your food is a skill that takes lots of practice: how to build the trap, where to set it up and what to do if you're fortunate to find something edible in the trap. Have you ever prepared a live rabbit for dinner?

In reading the earlier posts on this thread I get no feel for your knowledge and experience in any of the many survival skills. It's not something you just pick up by reading a few posts on the internet. Until you actually practice the skills by themselves you don't own them and until you own them, you aren't ready to make your survival video.

If this video is something that needs to be done soon, break it up into segments on the different needs a person in a survival situation may have. Start with a segment on the small kit you build to carry any time you are out hiking. Discuss what all the different components are for. Do a segment on building a shelter, then a segment on building a fire and a segment on using that fire to boil water from a stream because otherwise it's not safe to drink. These segments should build on previous segments and use the items in your kits. You might do a segment on using a map and compass for navigation (so you don't get lost in the first place). Have fun, but don't jump in with a three day camping trip that could be miserable.
