The Hunt for M

I have a edition of M at my home with a documentary called The Hunt for M from the year 2003 on a second disc. However, I could not find this documentary on IMDb not even after searching for the director, Torsten Kaiser. I could not find it on Google, Wikipedia or Letterboxd either. I found every movie, that I searched for before on IMDb, even making-of documentaries. If someone finds some kind of link that would be awesome.
