Last year, for the 60th anniversary of his death, Alan Turing started appearing in various publications intended for high school teachers of English, at least in France. Before that, I don't think I had ever heard his name. I now know he was a mathematician, pivotal in cracking German WWII codes, and counts as a precursor in computer science.
This film will tell you all of the above (except for his appearances in French schooling documents) in two entertaining hours. My ten-year-olds both enjoyed it, albeit not as much as I did. Wholesome family fun, then! (OK, perhaps more educational than fun.)
I am so going to get this on DVD and show it to students! Apart from the fact that it fits nicely into the work on the Blitz I generally do with my last-years, and its obvious didactic value, it also skilfully raises the issues of outsidership, feminism, friendship, tolerance and homosexuality.
Plus, it's directed by a Scandinavian.
