Whether you mean the movie or book series, it’s true that VC began its life as a short story which AR expanded into the first novel [X]. After it received so much positive feedback, there was a sequel, and then another, and then another, and here we are with a whole series!
The IWTV movie took something like 20 yrs in production and talks and film industry issues before it could finally get made. The homosexuality and the whole pseudo-pedophilia edge (Louis biting Armand’s Denis, Claudia in general) also made the story and casting extremely difficult.
At one point, I think Tom Cruise had the rights, and was down for making a sequel to IWTV, but I think the homophobic backlash pretty much turned him off the project 😦 It just seemed to ruin any sequels from happening for awhile.
Movie!QOTD was released in 2002, and iirc, doesn’t have much of the controversial issues that were in movie!IWTV, and is almost a stand-alone story due to how much it distorted canon, but some ppl really love it and find it nostalgic anyway!

^Akasha bc of reasons.
