Very few characters are seen wearing (or caring about having to wear) a mask. This is because at the beginning of the Covid19 pandemic the French government urged its population not to buy any so as to provision hospital staff. Even with this policy, health-care professionals were running low on mask supplies.
Dany Boon already played a hypochondriac character in "Supercondriaque" (2014), also directed by him.
Dany Boon and François Damiens starred together in Ils sont partout (2016) and Rien à déclarer (2010).
