Previously, Rockstar was sued by Lindsey Lohan for allegedly basing a Grand Theft Auto 5 character off her likeness. The 38-year-old actress ultimately lost that legal battle, so it's highly unlikely that Rockstar changed the NPC's appearance to avoid a lawsuit.
What probably happened here is that this is just the natural progression of the game's graphics and visual assets. Keep in mind that the first trailer was released back in December 2023, and work continued tirelessly on the game since.
Based from the improved graphics that we've seen so far, the characters and locations went through a glow up, or so to speak. If you compare what Jason and Lucia looked like in the original leaks from September 2022 to the first trailer and the latest trailer, it's evident that the changes are just a form of extra polishing.
With that said, it'll be interesting to see what the final outcome of the characters and locations we've seen in the GTA 6 trailers so far will be.
Certain NPCs from the first trailer, like Stefanie and the Florida Joker, didn't appear in the second trailer, so we can look forward to them sporting a more refined appearance by the time the game is released.
GTA 6 is currently scheduled for a May 26, 2026 release on the Xbox Series S/X and the PlayStation 5.
