Nyong’o also shared a picture with her costar Oscar Isaac, captioning it “La Fuerza Despertada. Oscar Isaac.”

In Star Wars: The Force Awakens, Nyong’o plays Maz Kanata, a small alien creature. Talking about casting Nyong’o in the part, director J.J. Abrams revealed it was difficult for him to develop the character’s look.

“You cast someone as beautiful as Lupita, and you have her a motion-capture character?” Abrams said at a recent press conference. “I’m like, ‘Would it be okay if she were ugly?”
