Marco Mazzoli (who plays Antonio Graziani) is the host of Italy's #1 radio show (Lo Zoo di 105).
Dolph Lundgren filmed this project after 'Aquaman' (2018) and before 'Creed II' (2018).
In 2014, the project was entitled "The Stranger". Actor / producer Walter Nudo and director Georgio Serafini approached Dolph Lundgren then but nothing happened and it stalled for a few years until the production reignited in late 2017 / early 2018.
