Taking nothing away from what Dan says, if you do want to go down the route of training films, have a look at Edward Martins ones from Sealpin Kennels. The reason I suggest his is because it is more than obvious that some of the other professional trainers have used already trained dogs in the making of their films which kind of defeats the purpose in my opinion. Edward does the opposite and shows you dogs making basic errors so that you see how to correct them. From the puppy choosing stage right up to their first time out in the field picking game, you will see the dogs developing. I can vouch for him as a friend and I helped in a small way when the films were being made (I receive no royalties!!!) by taking some of my pups down to his kennels to highlight what to look for when choosing a dog.
Like Dan says though, when I started training dogs I learned from mistakes and by reading what was available at the time.
