[X] Anon, looking at her question, I really don’t think this shows a lack of care for her characters, it shows AR looking for intriguing ways to tell these stories and seeking feedback on her ideas.

Lestat did compare Nicki and Louis, and there are similarities and differences, I think AR was just curious about it as an idea… I’m sure this has been done in live theatre at some point, casting one actor for 2 (or more) roles in a given production. She did say she’d want a talented, versatile actor who could create each role distinctively.
But yeah, I personally would prefer they were separate actors rather than introduce the idea that Louis was merely Nicolas in disguise or something weird like that.*
Hey, at least she’s listening to the fandom! We have to give her credit for that. Not every idea is going to be a great one, and we’re fortunate that even when we shoot her down, she keeps brainstorming, unfazed by the negative reactions she might get *u* I think that shows enormous character on her part, especially considering how she USED to react to negative reactions or even moderately critical reviews of her work.

… I would, however, accept a Claudia who was played by the same actress who plays Lestat’s little sister (presumably a sister, the mysterious unnamed 8th de Lioncourt!) bc that could have super adorable and haunting potential!
