Darkhorse Casting: Averted. The actress who played Nico, Sarah Crook did not actually audition for the role. She was one of the supervisors of the audition, and asked Charles Cecil if she could try out for the role after a string of applicants Cecil regarded as unsuitable.
Also, a lot of the random junk you could examine in the original is taken out in the Director's Cut, averting it here as well. A lot of the time, it really is just some funny observations or unimportant descriptions. But an entire character gets cut at one point.
At one point in Sleeping Dragon you find a "large iron key" twenty feet away from a "large iron gate". Response to using one on the other: "There was no reason to try that"... A Red Herring is one thing, but you'd think it could at least get a unique line of dialogue.
Executive Meddling: The Sleeping Dragon and The Angel of Death had a fair share of meddlings. Revolution wanted to create those games in 2D but publishers demanded that they should be in 3D.
As for the third game, the reason why there are lots of crate puzzles is that there's a lack of general time and funding pressures to create the game.
Franchise Zombie: The series had originally been designed as a trilogy with The Sleeping Dragon intended as the finale, but fans persuaded to create another sequel which was The Angel of Death. The fan reception, however had negative to mixed reviews after its release.
Official Fan-Submitted Content: In The Serpent's Curse, ten fans had an opportunity to interview George by sending their questions via voicemail. The interview is an Easter Egg that can be found in Castell del Sants.
The Other Darrin: Several secondary characters whose original voice actors were either dead or unavailable.
Most notable is Nico's English voice. She has been voiced by a different actress in each game: Hazel Ellerby in The Shadow of the Templars and Director's Cut, Jenny Caron Hall in The Smoking Mirror, Sarah Crook in The Sleeping Dragon, Katherine Pageon in The Angel of Death (also known as Secrets of the Ark), and Emma Tate in The Serpent's Curse.
Relationship Voice Actor: Rolf Saxon and Hazel Ellerby are friends and schoolmates in real life. Hazel reprised her role as Nico for Director's Cut.
Release Date Change: The PC version of The Serpent's Curse episode two was supposed to be released in January 2014 but bumped ahead to April 2014.
Talking to Himself: In the second game, Rolf Saxon also voices as a goat in Quaramonte City.
In Director's Cut, Hazel Ellerby plays both as Nico and Imelda Carchon.
Voices in One Room: In The Sleeping Dragon, the voices were recorded with the voice actors together enabling better acting and interaction.
Write Who You Know: One of the minor characters of The Shadow of the Templars Albert the Concierge was inspired by a concierge who shouted Charles not to make so much noise in forecourt at night and then started ranting about the English.
