The music playing when Canaletti is confident enough to invite Francesca for a date is a clear variation of The White Stripes' "Seven Nation Army".
Katia Bellini is the only character in the movie that has the same name as its counterpart in the original movie Look Who's Back (2015), there portrayed by Katja Riemann, even if spelled "Katja" instead of "Katia".
Alessandra Mussolini, Mussolini's real life granddaughter and EU Representative of the conservative Party "Forza Italia", praised the movie by saying "I really liked it. It's a movie that doesn't put words into my grandfather's mouth he never said. it simply records people's reactions in seeing him alive."
Katia Bellini represents an actualization of Margherita Sarfatti, that was an outstanding figure in Italian cultural life, and that mentored Mussolini's political ascent in the years around 1920 and following.
