Item: Colonia Dignidad - Es gibt kein zurück
Type of Problem: Incorrect_content
Extra Details: Wrong German title. "Colonia Dignidad – Es gibt kein zurück" is wrong. "Colonia Dignidad – Es gibt kein Zurück" is right, with capitol "Z". See IMDb https://www.imdb.com/title/tt4005402/ and Wikipedia https://de.wikipedia.org/wiki/Colonia_Dignidad_–_Es_gibt_kein_Zurück

Thanks for your report!

Both IMDb and Wikipedia are not official sources for the film!

So, I looked for official sources. Unfortunately, they always write all in caps: "ES GIBT KEIN ZURÜCK":

• official website: http://www.coloniadignidad.de
  
• official facebook: https://www.facebook.com/coloniadignidad
  
• press server of German distributor: http://www.majestic.de/colonia-dignidad-presseserver-2
  

All I could find on these pages is the version in all caps. However, the German DVD/BluRay distributor uses "zurück":

http://www.fox.de/colonia-dignidad#dvd

And I took a look in my old East-German Duden -> their rule is "zurück". And then I took a look in my new German Duden - their rule is "Zurück".

So, you see, it's pretty much a dead-end discussion. I'll keep it as it is with "zurück". If another moderator wants to change it, I won't object -> it doesn't really matter in my opinion.
