"Real" and "hunting shows" don't belong in the same sentence. I've been in or have shot video for about 6 different shows over the years. These ranged from shows on the outdoor channel to Sports Southwest, OLN etc. It has been my experience that a good 85% of the 30 min show (actually 22 min + commercials) is acting.
How often do you see a show where no matter what size of buck they kill the "hunter" acts like it's either the biggest one they've ever killed or they are "amazed" that they actually got this buck? It's acted.
Most of these shows require that the guide/outfitter supply an animal for the "hunter" and the crew. The producers of these shows have a lot of time and money tied up in these shows, not to mention all of the product placement that has to be done during the show ("boy, i'm just glad i had my Widgit 5000 along on this hunt or I might not have got that deer").
Sometimes, I've seen this twice on videos I've been a part of, you get your animal too quickly and dont have enough "filler" to make your show so you have to act part of it. A lot of this is done with stalking scenes or the sitting around the campfire scenes.
Also, notice how almost every "hunter" talks in a hushed whisper even when they just got out of a F-350 or off of their 4-wheeler?
These shows are a business. That business is to sell you something, usually with gross overstatements and product placement. Notice how many gadgets hunters swear they have to have to be a successful hunter these days? How was it even possible to hunt before we had cammo rangefinders, scent lock clothes, and a decal of a buck on our trucks?
