"It was really uncomfortable to sit in the theater and listen to people laugh at my father," Shannon expressed.
"Once Upon a Time in Hollywood" may have been well-received by film critics and cinephiles alike, but one person was definitely not a fan of Quentin's Tarantino's latest work: Bruce Lee's daughter, Shannon.
While speaking to The Wrap Monday, Shannon slammed Tarantino's portrayal of her father in the film, saying it was "disheartening" seeing Lee depicted as an "arrogant asshole."
At one point in the film (spoiler alert), Brad Pitt's stuntman character, Cliff Booth, and Bruce Lee (Mike Moh) challenge each other to an informal fight -- best two-out-of-three -- while on the set of "The Green Hornet" TV show. Although Lee easily wins the first round, Booth throws Lee into a car in the second. The duo is interrupted before they go at a third round.
"He comes across as an arrogant asshole who was full of hot air," Shannon said of the scene. "And not someone who had to fight triple as hard as any of those people did to accomplish what was naturally given to so many others."
She added, "Here, he's the one with all the puffery and he's the one challenging Brad Pitt. Which is not how he was."
Shannon admitted she didn't have a problem with Moh playing her father, however, said it seemed he "was directed to be a caricature."
Although Shannon said she understands Tarantino's reasoning for her father's portrayal, it didn't make it any easier for her to watch, especially due to what her father had to go through as an Asian-American actor in the 1960s.
"I can understand all the reasoning behind what is portrayed in the movie," she said. "I understand that the two characters are antiheroes and this is sort of like a rage fantasy of what would happen...and they're portraying a period of time that clearly had a lot of racism and exclusion."
"I understand they want to make the Brad Pitt character this super bad-ass who could beat up Bruce Lee," she continued. "But they didn't need to treat him in the way that white Hollywood did when he was alive."
Shannon added, "It was really uncomfortable to sit in the theater and listen to people laugh at my father."
This isn't the first time Lee's daughter has spoken out against "Once Upon a Time in Hollywood," which is Tarantino's ninth film. Shannon criticized the director before the film was even released, saying she was angered she wasn't contacted about Lee's character in the film.
Unlike Shannon, Tarantino reportedly got the okay from Sharon Tate's sister when it came to the late actress' character, portrayed by Margot Robbie.
"With Tarantino's film, to not have been included in any kind of way, when I know that he reached out to other people but did not reach out to me, there's a level of annoyance," Shannon told Deadline in June. "There's part of me that says this is not worth my time and my energy. Let's just see how the universe deals with this one."
"Once Upon a Time in Hollywood" is in theaters now.
