As a 17 year old Australian in High school, I hope I can help..
I only started watching F1, like Herman, in 2008 and beforehand I had no idea, let alone much interest, in who Senna was. Quite frankly unless the students are interested in F1 or motorsport in general most wouldn’t make any connection with the movie. To most of my friends, F1 is just ‘Cars going around in circles’ and the only good bits are the crashes.
For the film to have an impact on people I think first you should do a lesson, even just 10-15 minutes before watching the movie, showing YouTube videos of classic F1 moments. Show some crashes, classic battles, the kinds of things that get 14-15 year olds interested and then find a way to relate it to Senna and the topic.
One of the things I find with teachers is this..
Teachers that the students can relate to and respect will be given time to explain their point and the students will listen, taking what they are saying and teaching in, while those that don’t respect the students are barely given the light of day and the message that they are trying to teach is largely ignored.
My Physics teacher is a classic example of the former. In class we do barely any work, he talks to us, not at us, and we watch Youtube videos (Duck Song anyone.. http://www.youtube.com/watch?v=MtN1YnoL46Q ) and class is generally fun and the students respect him. However when he goes to teach us something, the whole class is silent and we take in every word that comes out of his mouth and we learn a great deal. Compare this to other teachers and the difference is unreal.
If the students can relate to you and respect you like this then they would watch just about any movie you put on for them. If they don’t, Good Luck!!
