Vivian Kubrick, the daughter of legendary director Stanley Kubrick, unleashed a blistering social media tirade against Erika Kirk, calling her speech “ghastly,” “inauthentic,” and deeply unsettling in a post that quickly stirred backlash online.

“I HAVE NEVER WITNESSED SUCH A GHASTLY INAUTHENTIC PHONY PERFORMANCE IN MY LIFE AS THIS SPEECH BY ERIKA,” Kubrick wrote, adding that despite her upbringing in the entertainment world, she had “been around a lot of phonies” but felt compelled to speak out.

She went further, accusing Kirk of being “a threat to my country,” suggesting she resembled “a military or intelligence operative,” and labeling her “definitely some kind of sociopath.”

Kubrick described a visceral reaction to Kirk’s public appearances, saying, “there’s something seriously wrong with this woman – every cell in my body shudders listening to her voice and watching her face.”

Kubrick also referenced past moments that she found disturbing, including Kirk’s remarks at her husband’s memorial, where she said, “that young man … I FORGIVE HIM!”

She additionally pointed to a video Kirk shared of herself lying across her late husband’s body, calling it “way beyond wildly inappropriate” and “horribly sinister.”

The filmmaker’s daughter then turned her attention to Turning Point USA, the group co-founded by Charlie Kirk, urging political leaders to cut ties.

“MR PRESIDENT – If we’re to win the midterms, you need to ‘kill’ @TPUSA and let some honest to God, authentic, super smart young patriots rally the American youth,” she wrote, adding that no one could replace Charlie Kirk within the organization.

Her remarks surfaced amid heightened attention on Erika Kirk, who recently addressed supporters via a pre-recorded video instead of appearing in person at Prestonwood Baptist Church in Plano, Texas, as part of Turning Point USA’s “Make Heaven Crowded” tour.

Kirk told the audience she was taking time to be with her family following recent events.

Days earlier, she had attended the White House Correspondents’ Association Dinner, where a man attempted to storm the event with guns and knives and was later charged with attempting to assassinate President Donald Trump.

In a separate social media video released Wednesday, Kirk spoke about what she described as an “epidemic of dehumanization” in the United States.

During her Plano address, she delivered a sermon-style message reflecting on her husband’s death and her own resilience, drawing parallels to the biblical period between Jesus Christ’s burial and Easter Sunday.

Charlie Kirk, CEO and co-founder of Turning Point USA, was assassinated in September while speaking at a college campus in Utah.

His memorial drew national attention, including attendance from President Trump, where Erika Kirk publicly forgave the accused killer.

Kubrick has previous made headlines for her politics. She has stated that she is “very confident” her late father, Stanley Kubrick, would have supported Trump.

Her claim followed controversy over Trump’s use of footage from Full Metal Jacket in a campaign video captioned, “WE WILL NOT HAVE A WOKE MILITARY!”
