Just the fact that the cover is a drawing, like those old B-movies should give you a warning about the quality of this movie. This is, however not a B-movie. It is a D-movie!
There are no known actors, and the animals - WOW - it is the worst data-animation ever made during the last two decades.
You hardly ever see the SCAAARY sabretooth shown on the front cover. You just hear people scream, bleed and die and you occasionally see a teeth or a tiger-paw. It's so amateur! Maybee worth seeing, just because it's so bad. Give it to a friend and say: "This is the best movie I have ever seen, and wait for their reaction" He, he.
The movie is to weak to give it a Spoiler Alert! THIS IS A SPOILER.
