That may well be. There’s no way to know if this is authentic. But on the other hand, this is exactly to be expected from a film adaptation, if you’ve ever seen a film after reading the book. Honestly, I really expect that a Borderlands movie will disappoint fans of the game.
You wouldn’t expect it to use the game’s story, which would be super boring, but as a fan, you don’t want it to invalidate the story or the characters - that clearly wouldn’t be welcomed by the fans of the game, who wouldn’t consider it to be canon.
Alienating an existing fan base like that is the problem with films based on games. If a filmmaker made a movie respecting the canon, that integrated itself into the existing universe, it would be viewed by the fans as an extension of the game’s story told through a different medium, like the Borderlands comics and film shorts. Re-imagining the basic story and characters would be a waste for both the filmmakers and the fans. But again, that’s really what you should expect, given the history of game films.
