Mammon has been renewed for a third season. NRK has not yet given the all clear, but states the scripts for the third season are in progress.
The film poster visible in Peter's home is for Next Door (2005), a Norwegian horror film featuring Anna Bache-Wiig who plays the character Inge Marie Steffersen in this series.
Mammon won two awards in 2014 at the Seoul International Drama Awards: Best Director and Best Mini-Series.
