A filmmaker has just sued Netflix, LeBron James, the NBA star's production company and a host of others ... claiming they stole one of his scripts -- and then used it as the basis for one of their recent hit basketball movies.
Rob Grabow -- a screenwriter who directed the 2023 drama "The Year of the Dog" -- spelled out the allegations in a 25-page lawsuit ... that was filed on Thursday in a California federal court.
Grabow states he had written a script for "The Gift of the Game" -- and it was all about a Native American high schooler and his efforts to lead his basketball team to a state title.
