* DoingItForTheArt: Tom Ford self-financed the film version, and even had to personally ask Colin Firth to accept the part.
* FakeAmerican: Matthew Goode and Creator/NicholasHoult, who are both English.

* TechnologyMarchesOn: While in the loo George knows Charley is calling him and, in the book, laments the fact there isn't a phone cord long enough for him to speak to her from there. Ignoring the fact, even with a corded phone, a person could put a phone in the bathroom, there are now cordless phones, and many people do take mobile/cell phones into the bathroom with them for various reasons.
