Tolo on the movie The Long Shot

What is the name of the horse that plays Tollo in the movie The Long Shot? It is about a horse that is a high level dressage horse that becomes blind yet still competes with his rider... the horse is an EXACT match for a rescue horse I have (who is also a high level dressage horse). I cannot find any credits anywhere that say who the horse(s) is/are.... can anyone help?
