Christina Ricci said in a 2022 interview that she had no problem being totally nude so much during filming, but what made her uncomfortable was other people being uncomfortable with her being naked. That made her feel really weird. So what she did, which she admitted actors probably wouldn't be allowed to do these days, is just stay naked and not wear a robe between scenes. She'd also go talk to crew members naked because she wanted everybody around her to stop reacting to it, because then she could forget that she was naked. Doing that made it one of the only times she's really felt comfortable being naked on camera.
Shot in 25 days.
