Of course, "The Miracle Worker". There is the same disease, same physical struggle with a stubborn teen to force her to learn, but in French not English.
I appreciated the photography and the location but I continually had to resist the temptation to check my watch. It might be just over 90 minutes but at times it seemed like hours. It would drag and drag and then suddenly leap forward after she learns the sign for one object. The next thing we know is she is showing off how she can spell her name and understanding abstract concepts like 'patience'. There was also the monologue at the end which seemed especially message-y.
I liked the acting by Isabelle Carré and Brigitte Catillon but Ariana Rivoire as the deaf/blind girl didn't impress. Possibly it was just because she had so little to work with.
To sum up, see "The Miracle Worker" instead.
