Frank Lammers had to lose weight because he is playing a younger Ferry and had to look more fit.
The prequel of the Netflix-serie Undercover
When Ferry drives through Amsterdam, buildings in the background -the business district 'Zuid As' of Amsterdam-are seen which haven't been build in 2008.
On the campground arrives a car with trailer and the driver wears a face mask. Movie was filmed during corona period, but in the story itself they never heard of Covid19 of course.
Set in 2008 Ferry would not have a bottle of Jack Daniel's Honey edition at his home as it was not launched until 2011.
