Harley Quinn Smith

Harley Quinn Smith is an American actor and musician who has steadily built a career across film and television, often in projects with a cult following and a distinct, offbeat tone. She is best known for playing Mallory Higgins in Cruel Summer, a role that brought her wider attention and showcased her as a grounded, emotionally sharp screen presence. She has also appeared in Once Upon a Time in Hollywood and has worked repeatedly in films connected to her father, filmmaker Kevin Smith, including Jay and Silent Bob Reboot, Yoga Hosers, and Clerks III.

Smith has spoken publicly about living vegan and has described it as a deliberate shift that followed years of vegetarianism, placing animals at the centre of her decision. She has also been open about the everyday reality of maintaining a plant-based lifestyle while working on set, from relying on simple staples to making sure catering works for her.

She has also taken that commitment into her public work by co-hosting Vegan Abattoir, a show that answers common questions about vegan living. In interviews, she has spoken about convincing her father to go vegan after his 2018 heart attack, framing it as a direct and non-negotiable change.
