There is an actual property in Australia named Brindabella Homestead (more commonly known as Brindabella Station), located in the Brindabella Ranges in New South Wales. This property is best known as the childhood home of author Miles Franklin, but it has no connection with the TV series except for the shared name.
The on-screen names for the characters are the same as those used in the board game, but the characters are assigned a given name that is often used in the filmed scenes and the characters' interactions with the audience - Mrs. Peacock is Elizabeth, Col. Mustard is Mike, Rev. Green is Clem (his full name is revealed in one episode as Clement Ashley Green), Prof. Plum is Peter, Miss Scarlett is Vivienne and Mrs. White is Blanche. Most of these are the same given names used by the British series Cluedo (1990), except that they used Jonathan instead of Clem for Rev. Green.
The Crawfords studios that were used for the interiors of Brindabella Homestead were demolished in 2006. The site, on the corner of Middleborough and Clarice Roads in Box Hill South, is now occupied by a Bunnings Warehouse (an Australian home improvement store chain).
Over the 25 episodes produced, Col. Mustard committed the most murders with six, ahead of Mrs. White with five, while Rev. Green and Mrs. Peacock tied for the least murders committed with three each. Four culprits committed murders in back-to-back episodes, with Mrs. White being the only one to do so twice, both in the second season, with poison being used on both occasions in one of these occurrences (with poison in one and a poison phial in the other). The most common murder method administered through various weapons was poisoning, which was used six times, just ahead of blunt weapons and sharp weapons, which were used five times each, while some unique methods like drowning (in a divination pond) and falling (off a step ladder) were used once each. The billiard room was used the most often, with seven murders committed there, ahead of the library, which was used five times, while the dining room was used the least, with murders only taking place there twice.
Due to copyright restrictions, the Nine Network and Crawfords Australia sought assistance from Action Time, the British game show production company who produced Cluedo (1990). This led to the collaboration known as Crawford Action Time, who also hoped to produce Australian versions of six other British game shows and sell them to other Australian networks, but Cluedo would be the only series produced under this collaboration.
