Jean-Jacques Annaud's films always showcases animals doing extremely amazing things, which is why they are so enjoyable. While this is a film better seen by children of certain age group, it's not a Disney product, and parents should be aware of that fact. Some comments in this IMDb forum criticize the film makers for what they perceive was a marketing ploy that targeted the movie to small children. Perhaps the people that promoted the film are to be blamed for that, or maybe Mr. Annaud was targeting the film for a more mature audience.
"Two Brothers" is a story about two tigers that are separated at a young stage of their lives, while their parents are killed by people that loved to engage in this type of hunting. The two little cubs are about the best in the film as one see them getting in all kinds of adventures in the first part of the film.
The story behind the animals serves the film as it provides an accessible background as it illustrates the inter action between humans and animals. Guy Pearce and Freddie Highmore are seen in the film as Aidan and Raoul. Freddie Highmore is a child actor with an expressive face that shows a child of great intelligence without any trace of ego.
As Mr. Annaud proved with "The Bear", he has a good eye for involving the animals in his stories about them with surprising results.
