@sigross The wearers of the tattoos aren’t involved in the cases you mentioned. In both, the tattoo artists sued the movie/video game companies. The artists argued that they own the copyright of the design, not the person wearing it, and that the agreement made between tattoo wearer and the media company to reproduce likeness did not include the rights to reproduce the tattoo. Both cases settled out of court, with the media companies paying the artists money.
For the Hangover case, I believe the issue was not about Mike Tyson himself appearing with the tattoo, but another actor with the design recreated on his face. The artist wasn’t arguing that Tyson couldn’t show his face on film or anything to do with his body.
There was another case last year between tattoo artist and a video game company that licensed the likenesses of NBA players. The judge ruled in favor of the video game makers because the work was transformative enough, and also agreeing with you, the tattoos are included in the person’s likeness. Here’s a Sports Illustrated article about it: https://www.si.com/nba/2020/04/06/nba-2k-ruling-tattoo-artists
It would be interesting if the guy wearing the Miles Davis tattoo appears in a video game, and which artists would get to try to sue the video game company haha
