Festival Eurovision da Canção: A Saga de Sigrit e Lars

To prep for the film, Will Ferrell attended the 2018 The Eurovision Song Contest (2018) in Lisbon, Portugal as part of the Swedish delegation and was given access to follow the show from start to finish, including rehearsals.

The five biggest financial contributors to Eurovision go straight to the final without going through the semi-finals. These countries are Spain, France, Germany, Italy and the United Kingdom, the so called "Big Five". In the film, Spain and the UK sing in the semifinals, something that has never happened in the history of the festival. The result screen also shows all the Big 5, while in the real contest they would only be shown at the finals. Also, the host country has a guaranteed place in the final too. Since the contest was being held in Edinburgh, that means the UK would have been in the final anyway even if it wasn't already a member of the Big-5.

In the final credits, the actors' names are shown with the flags of their native countries.
