Another Olsen Girl: Elizabeth Olsen Steps Out, To Star in Film

Babble.com noted that in her last film "The Adventures of Mary-Kate & Ashley: The Case of the U.S. Space Camp Mission" released 1996, she played herself.

Elizabeth has acted in three movies and played herself in four of her sisters' videos. Her acting debut came when she was 5 years old, when she played "girl in car" in "How the West Was Fun."

Her existence, though, was a shock to some.

"WHAA???? There's another Olsen????" Gawker.com Defamer blogger Richard Lawson wrote. He said while the movie sounds interesting, it's "not as interesting as the sheer fact of this mysterious and shadowy Olsen sister ... ."

Lawson stated that he has written several biographies of the Olsen twins and did not know about Elizabeth.

While sister Elizabeth has been acting, 24-year-olds Mary-Kate and Ashley have been focusing their energy on their high-end fashion label The Row, according to People StyleWatch . The twins have released a fall collection with "muted classics" like a black wrap coat, an expertly-tailored white shift and a perfect lazy-day jumpsuit.

While stars like Jessica Biel and Charlize Theron have been seen in fashions from The Row, the sisters are still hopeful to add First Lady Michelle Obama.

As for the twins movie career, IMDb stated that Mary-Kate will appear in the just completed movie "Beastly", described as a modern-day "Beauty and the Beast" story. She will also appear in "Story of a Girl," a move currently in pre-production.

And according to IMDb Ashley's last movie was "New York Minute," which also starred Mary-Kate and was produced by the twins in 2004.
