This beautifully animated film from Disney Pixar is wonderfully wild, rugged
and dramatic.

Teaching ideas
Firstly without the voice-over, I ask
the children to write descriptions of the hero, the landscape and the bear. 
 I include discussions about the trailer and  the girl.
I also ask the children to write a new voice-over that they can read out while the trailer is being played. This is extremely challenging for the children. Their writing has to be long/short  enough to fit with the action. They need to use a range of long descriptive  sentences and some short, dramatic sentences that add to the tension in the  trailer.
The children can write an extended narrative based on the trailer. They can  produce this in various text types. 1st or 3rd person narrative, fairytale  style, newspaper report, etc
 I have had some exceptional results with this film.
