Trivia: Lemtov says everyone hates the UK - this is harsh but fair in Eurovision terms, as the UK hasn't won since 1997 and regularly has a disappointing score, with some theorising political reasoning plays a part. Lemtov is played by Dan Stevens, who's British.
Trivia: Iceland has never yet won the Eurovision song contest.
Trivia: The "song off" features many appearances from previous Eurovision contestants.
Trivia: The film was meant to be released to coincide with the 65th Eurovision song contest in 2020, which ended up being cancelled due to the Covid-19 outbreak.
Trivia: Will Ferrell was interested in Eurovision from the late 90s - he always felt someone should make a film about it, and was surprised nobody else ever did. So he finally did himself.
Trivia: The film starts with ABBA performing Waterloo. Pierce Brosnan starred in the ABBA musical Mamma Mia! and performed Waterloo over the end credits.
Trivia: Graham Norton, the commentator during the semi finals and final, is the official Eurovision presenter for the UK. The sardonic comments he makes during the film are exactly in line with the sort of comments he makes during the real broadcast, a tradition which started with his predecessor Terry Wogan, who started the role in 1980.
Trivia: Pierce Brosnan is only 13 years older than Will Ferrell.
Trivia: Rachel McAdams doesn't perform all the songs herself, which are mostly sung by Swedish singer Molly Sanden. However McAdams' voice was used for mixing, and she sings in the first rehearsal, plus when she's writing Husavik in her hotel room. Likewise Dan Stevens, whose singing is performed by Erik Mjones.
