"Little known fact: most male actors don’t want to play supporting roles in female-led films. The industry has raised them to believe it lessens their power (i.e financial value) to accept these roles, which is one of the reasons it’s so hard to get financing for movies focusing on female stories."

She continued, ""Enter: @harrystyles, our 'Jack' . Not only did he relish the opportunity to allow for the brilliant @florencepugh to hold center stage as our 'Alice', but he infused every scene with a nuanced sense of humanity. He didn’t have to join our circus, but he jumped on board with humility and grace, and blew us away every day with his talent, warmth, and ability to drive backwards. 👊 #dontworrydarling."

Wilde also stuck up for Styles on Instagram when Candace Owens bashed him for wearing a dress on his Vogue issue. Many other celebrities also expressed their support for the singer.
