I was excited to see Beastmaster when it came out. I was extremely disgusted when I actually saw it.
It's a horrible mangling of the book "Beastmaster" by Andre Norton.
It's a scifi story with the main character being an ex-military esper who lead a beastmaster sabotage team, and was also a descendant of terran american indians. As to the ferrets, they were supposed to be a pair of meerkats.
If you want to know more, just read the book, I'm sure your local library has it.
Also, here's a link to a small wiki article on it, but still, read the book. http://en.wikipedia.org/wiki/The_Beast_Master
The Goonies, Raiders of the Lost Ark, Indiana Jones and the Last Crusade, Ghostbusters, Stargate, Atlantis: The Lost Empire, Treasure Planet, Pirates of the Caribbean: Curse of the Black Pearl... I'm sure there's a bunch of others I can't remember.
I feel deprived that I haven't seen (or heard of) a few of the movies on that list. I'm not sure how I missed them, since they aren't any older than the ones I have seen. Of course, it might be painful to watch them now for the first time. Nostalgia is powerful magic.
There is a Russian movie from 2006 called Wolfhound that is an excellent source of ideas and would definitely recommend. Also, an animated movie from 1982 called The Flight of Dragons had quite a few big names, and it's what inspired me to get into fantasy when I was a kid. Definitely a must watch movie.
