Lively sparked outrage among sexual assault survivors for defending Woody Allen.
Lively's 2016 film "Café Society" was directed by Woody Allen.
Two years before "Café Society" premiered, The New York Times published an open letter by Dylan Farrow, Allen's adopted daughter, reiterating the accusation that he groomed and sexually assaulted her as a child.
Farrow originally accused her famous father when she was 7 years old. At the time, a state's attorney in Connecticut said he had "probable cause" to prosecute but declined to file charges.
In the 2014 essay, Farrow called out Hollywood stars like Cate Blanchett, Emma Stone, and Scarlett Johansson for working with Allen in recent years and ignoring the allegation against him.
"Woody Allen is a living testament to the way our society fails the survivors of sexual assault and abuse," she wrote.
During the press tour for "Café Society," French comedian Laurent Lafitte cracked a joke about Allen dodging accountability during the opening ceremony for the 2016 Cannes Film Festival.
Later at the festival, Lively made it clear she disapproved of Lafitte's material.
"I think any jokes about rape, homophobia, or Hitler is not a joke," Lively told Variety. "It was more disappointing for the artists in the room that someone was going up there making jokes about something that wasn't funny."
At the same event, Lively also said she hadn't read Ronan Farrow's new op-ed in the Hollywood Reporter, in which the investigative reporter defended his sister and criticized powerful people for "sweeping aside her allegations."
"I don't want to speak on something I haven't read," Lively told Vulture. "I think that's dangerous. It's definitely something that being at the festival, the media these days, you come to a film festival about film and people talk about all different types of things. You know? That can be definitely tricky to navigate."
Lively continued to praise Allen throughout the press tour, describing his director style as "very empowering."
"It's amazing what Woody has written for women," she told the Los Angeles Times, adding that she did not consider Allen's personal life while shooting the film.
"It's very dangerous to factor in things you don't know anything about," Lively said. "I could [only] know my experience. And my experience with Woody is he's empowering to women."
In 2017, Farrow published another op-ed in the Los Angeles Times that questioned Allen's role in the #MeToo movement, casting Lively as a hypocrite for condemning Harvey Weinstein but continuing to support Allen.
In 2018, Lively posted in support of Hollywood's anti-sexual harassment initiative Time's Up, writing, "I'm honored to be a part of this movement. The time is NOW!"
Farrow replied, "You worked with my abuser, @blakelively. Am I a woman who matters too?"
Farrow's account of her assault has remained consistent over the years, most recently in the 2021 HBO docuseries "Allen v. Farrow," while Allen has repeatedly denied the allegation.
