- All-Star Cast: In addition to the aforementioned Firth, Rush, and Bonham Carter, there are supporting roles played by Sir Derek Jacobi, Guy Pearce, Timothy Spall, and Sir Michael Gambon.
- Dueling Works: There seemed to be an effort to force the movie into this with The Social Network, both big-hitting, big-budget biopics trying to nab Oscars and pretty much the only two contenders for Best Picture. This went right into the actual Oscars ceremony: Social Network's synth version of "Hall of the Mountain King" was the music for the opening montage while the title speech was the backdrop of the Best Picture montage.
- Fake American: Eve Best was born in London.
- Fake Brit: The Australian Guy Pearce as Edward VIII. Although at the time, there was no separate Australian citizenship, Australia was merely a self governing part of the Empire and this is a subversion for Pearce, who was actually born in Britain (his mother is British) and moved to Australia when he was three.
- Fake Nationality: Jennifer Ehle was born in North Carolina. (Yes, this means that we have an American playing an Australian, an Australian playing a Brit, and a Brit playing an American. The mind boggles...)
- Playing Against Type:
- Timothy Spall as Winston Churchill. He is usually known for playing repulsive villains such as Peter Pettigrew and the villainous sidekick in Enchanted. Could be a form of Fridge Brilliance considering that Churchill was, especially because of his self-righteous defense of British imperialism in 1930s and other personal and political flaws, considered a repulsive villain by many of his contemporaries.
- Helena Bonham-Carter has personally stated that she plays the crazy people well. The last time she was a queen, she yelled "Off with their heads" every five minutes. But as the Duchess of York, she's an eloquent, articulate, caring and supportive mother and wife.
- Reality Subtext: The film's writer was himself a stutterer, who took great inspiration from listening to King George's radio addresses, with his parents assuring him the King once stuttered worse than him.
- What Could Have Been: Paul Bettany was the first choice to play King George VI, but turned it down. Hugh Grant was also offered the part (he had played a stutterer before) and Robert Downey Jr. was considered, for it too.
