Season one is a region one boxset and requires a multi region player. Seasons two three and four are German editions. The writing is in German but the language is in English. These will play on a UK player or multi region player. It is only the writing that is German. The discs are as originally recorded in English. These were my son's but he's autistic and struggles with the fact that he can't read the text so we've now bought the complete series on region one for him. All boxes cases and discs are in good condition. We are currently replacing all his German writing boxsets so more will be listed including the TV series Wildfire. From a smoke free home.
