Allison Williams

Allison Williams (also credited as Allison Howell Williams) is an American screen actor born April 13, 1988, in New Canaan, Connecticut. She first drew major attention on television as Marnie Michaels in HBO’s comedy-drama Girls (2012–2017), a performance that helped position her as a sharp, contemporary presence in ensemble storytelling.

Williams’ wider breakthrough arrived with Jordan Peele’s acclaimed horror hit Get Out, where she played Rose Armitage—an icy, pivotal role that brought prominent award recognition and cemented her crossover to film. Since then, she has leaned into genre work and has frequently been labeled a modern “scream queen” for her impact in high-profile horror projects.

Her filmography spans studio and event titles, including Peter Pan Live! as Peter Pan and the techno-thriller phenomenon M3GAN, in which she portrayed Gemma and also served as an executive producer. She continues the story as Gemma in M3GAN 2.0, while also appearing in behind-the-scenes and documentary-style credits such as Unveiling the Horror of Get Out and A Goodbye to Girls.
