Are you curious about Elizabeth Olsen, the red-hot newcomer (and sister of the Olsen twins) who became a Sundance darling this year with her debut in Sean Durkin's Martha Marcy May Marlene? On October 21, you'll be able to check out Martha Marcy yourself, but in the meantime, Vulture is happy to premiere a clip from the dramatic thriller. Olsen plays Martha, a woman who escaped a cult and is attempting recovery at the Connecticut summer house of her sister (Sarah Paulson), though memories of the commune and its charismatic leader (John Hawkes) still haunt her. In this clip, you'll get a closer look at Hawkes and the creepy hold he has on Olsen. Enjoy!
