- (still AA TF) 2025/06. Who's excited by the possibility that in 5 years we'll be using AI to make our own live action Tv shows, movies and even music videos with AP or mostly AR? Right now people on TikTok are remaking brief Tv and movie scenes with babies, toddlers and kids. Within 5 years we may have adult hand shrinking/regressing or aging, or a man or woman's head slowly aging backwards or forwards. Or the main one, adults regressing into kids and babies and their clothes slowly becoming oversized.
- If you want a TF sequence then telling an AI generator to make a multi-panel image is a good idea. It can give the subject, background, & art style more consistency than when generating each panel separately. A problem I had was that Stable Diffusion couldn't understand relational directions. Tell it "on the LEFT is a short woman and on the RIGHT is a tall woman" all you want, but it wouldn't understand. However, Perchance's AI generator got an upgrade, and now it understands this kind of instruction: - link - alt - I make a point of not asking for any particular artist's style by name - (AgeRegressionFan01, BBB)

comics
Lost in Space
- (teen to young adult FFed) 20 issues, 1991.
Official continuation of the 1960s Tv show, depicting the adults still in their prime but the kids all grown up. The evolution from screen to graphic novels came from "Dangerous" Will Robinson himself, Bill Mumy. And by all grown up, I mean especially the girls. Marketing needs required a certain sexualization of the female characters. Meaning? Judy and Penny Robinson were shown in tight, revealing costumes, which were often torn and/or soaking wet. Yeah, I know, we all grew up with a BIG crush on Penny Robinson, so this must be great, right? Most issues featured at least one girl "in the all-together" (with strategically placed word balloons for coverage), which would be hot if she wasn't standing there right in front of her FAMILY! The Robinson girls were either in bondage-like situations (tentacles) or quite literally in bondage when Penny and Judy were accidentally sold into prostitution.

words
continuity error (FF type)
- (looks like AA AP) unintentional "age change" appearances.
Motion picture examples where the actors grew too much during filming:
- movies - The Mothership - filmed 2021, unreleased. Matthew Charman.
After her husband vanished, mother and children discover extraterrestrial object underneath their home. Numerous child actors outgrew their roles after filming started.
- movies - Quiet Place Part II, A - 2020. It starts exactly where the first movie ends. The 3 year gap between films meant the Abbot's children have visibly aged over the course of a scene.
