Wes Anderson revealed that Gene Hackman was 'furious' about being paid the same as everyone else in 'The Royal Tenenbaums'.
Anderson's flat-rate payment model caused friction with Hackman, who initially did not want to do the film but eventually accepted the role and salary.
The flat-fee salary approach led to tension between Anderson and Hackman during production, with Hackman leaving without saying goodbye after filming ended.
Anderson's payment model of equal pay for the cast of 'The Royal Tenenbaums' is gaining popularity in Hollywood, with other projects like 'Asteroid City' and 'The White Lotus' following similar practices.
