Lena Dunham and Planned Parenthood hosted the Sex, Politics & Film Cocktail Reception at the Sundance Film Festival that was attended by the likes of Elizabeth Banks and Rosanna Arquette.

Sex, Politics & Film At Sundance

Banks jetted into Park City, Utah on Sunday ahead of the Planned Parenthood event. An outspoken supporter of reproductive rights, Banks recently starred in a video for the Center for Reproductive Rights’ Draw the Line campaign that’s fighting for women to have access to abortion clinics.

Banks was but one of the many famous faces at the event, which included Arquette, Rose McGowan, Chloe Sevigny and Natasha Lyonne.

“Thank you to all the radical chicks who joined @jennikonner & me to celebrate @plannedparenthood at #sundance (co-hosted by @refinery29.),” Dunham captioned a photo collage on Instagram. “Your voices have never mattered more, ladies #blessyou.”
