Avatar (2022 Re-Release) - 1 addition from the theatrical cut

• This Isn't Over: When the remaining humans are leaving Pandora at the end of the movie, a quick dialogue exchange has been inserted in the middle of the scene. It features a foreboding exchange between Parker Selfridge and Jake Sully. In this exchange, Parker steps out of the line and tells Jake, "You know this isn't over?" The music turns sinister for a brief moment. After Jake dismisses him, Parker gets back in line, the music returns to its original score, and the movie resumes as originally presented.
• This brief new addition has been retroactively inserted into the 4K home release for all three versions of the film, despite never being included in any of them before 2023.
