I would like to add something about the name of Scarlett. In the famous story of Robin Hood, there is the character Will Scarlett to be considered. He is often portrayed as being 'hot-headed', and a lover of fine clothes. He is commonly described as wearing red silk and it may be these things that gave him his name. One of the most famous depictions of Will Scarlett is played by Christian Slater in Robin Hood: The Prince of Thieves. He is portrayed as Hood's illegitimate younger brother, and in folklore and legend is often a nephew of cousin of Hood, though it is not known if he was a relation or not. Anyway - Just an interesting person who does justice to the name Scarlett that I thought would be worth mentioning!
In the board game Cluedo, Miss Scarlett (Miss Scarlet in the "Clue" edition of the game) is the stock femme fatale character. She is typically portrayed as young, sinister, and beautiful. She was played by Lesley Ann Warren in the 1985 film.
