I have created a short booklet that breaks the film of War Horse into 20 minute blocks. Each twenty minutes has a sheet to go with it and they are arranged sequentially in a booklet. Each section of the film students are asked to identify any new characters, settings and the story so far.... There are also 3 visual questions about the section of the film. My students found this to be very helpful in following the storyline, and understanding the sequence of the film.
The second item in this pack is a powerpoint that looks at the novel of war horse. It breaks down setting, characters, plot and theme. There are some embedded activities but it is a wonderful resource to have as an accompaniment to the film.
