Pablo Larraín's Spencer, which is described as an "imagining" of the events that transpired over Christmas at Sandringham with the royal family in 1991, debuted its first teaser poster on Wednesday. The dramatic image features Kristen Stewart's Diana in a massive strapless off-white ballgown, reminiscent of a wedding dress. The ornate gown, cinched at the waist by a white belt, is embroidered with gilded leaves and flowers along the bodice and includes tulle trim on the waistline. Stewart, wearing the late royal's signature coif, is shown bent over the gown, seemingly crying into it. NEON This is the third image Spencer has shared with the public. Our first glimpse at Stewart in character showed the star channeling Diana in a black veiled hat; the second put the royal's iconic sapphire engagement ring on display.

"The accent is intimidating as all hell because people know that voice, and it's so, so distinct and particular," she said. Something tells us she wound up mastering it. "It's one of the saddest stories to exist ever," Stewart continued, "and I don't want to just play Diana — I want to know her implicitly." Spencer opens in theaters Nov. 5.
