All I can say is, before watching the movie I did not have a hint indication who Annemarie Schwarzenbach was or what was her life story..and I have to confess that the movie was hardly a help to reach these data.. and even it was not successful to persuade me to do some research by typing few words on google website; however, all I can say is that the actress Jeanette Hain was great with her mute facial expression she really played well and showed a deep depression mental status, as it is in real.
After all , based on the script the movie has happened in turkey and Tehran as well as Afghanistan.. but believe me I am familiar with the area , it was all about an Arabic desert in morocco.. Turkish people and persian people are completely different in face and culture as well as in language which is not arabic..
I suppose for making a film like this- documentary type- a thorough research about all these minor elements is mandatory..
