The measurements were conducted in the multiplex cinema Cinestar in Mainz, Germany (located at 49° 59' 37.511" N 8° 16' 45.548" E) in two different screening rooms for approximately four weeks during the winter 2015/2016. Over the 8 weeks of measurement, 11 different films were shown multiple times resulting in a total of 135 separate screenings. Table 1 summarizes the films measured, categorized according to the German film classification system age recommendations “FSK” (“Freiwillige Selbstkontrolle der Filmwirtschaft” meaning voluntary self-regulation) along with the number of screenings. The average number of people present at each screening is given in the supplementary S1 Table. It can be seen that each age recommendation class was attended by approximately the same amount of people.
