During the Norway segment, it is stated that mass murderer Anders Behring Breivik, who was responsible for several terrorist attacks in 2011 that killed 77 Norwegians, was sentenced to a minimum of 10 and a maximum of 21 years in prison. It is also mentioned that 21 years imprisonment is the maximum penalty in Norway, regardless of how many casualties there were. Although this is true, it should be added that Breivik was specifically sentenced to containment. Containment or preventive detention means that although the initial sentence is 21 years, the imprisonment can be extended indefinitely, as long as the convict is considered a danger to society, so in practice this probably means life imprisonment.
Michael Moore was hospitalized with life-threatening pneumonia the week the film opened and had to cancel all his publicity appearances.
Michael Moore also filmed scenes in Estonia, which is the country with the lowest mortality rate among women during childbirth. The scenes weren't used, but Moore showed shots from them in Michael Moore in TrumpLand (2016).
