Dirk Back, who played Urmel in this play is an Urmel-Fan himself. A few years before, the author of the Urmel-Book Max Kruse asked him to record the audio version of the book.
In the opening credits the words ''Sat.1 präsentiert'' (Sat.1 presents) are written on doors of a wooden box. After it's opened a blue curtain is opened. This is a reference to the opening of the ''Augsburger Puppenkiste'', which play this movie is based on.
