It’s possible that Fox submitted a tax credit application for Lethal Weapon as well as Lucifer; considering that priority seems to be given to relocating projects, however, the odds of a tax credit for Lethal Weapon may be considerably lower than the odds were for Lucifer.
Lucifer is the only drama that Fox renewed during the application window, but freshman series Lethal Weapon landed the order for Season 2 shortly after the window closed.
Lethal Weapon actually already films in Los Angeles, but the show does not currently receive a tax credit.
