Wednesday night, Elizabeth Olsen stopped into "The Tonight Show" to promote her new film, "Silent House." Yet, the ingenue ended up talking about some film roles from times past -- including her cameos in "The Adventures of Mary-Kate & Ashley."
When she was still just a tyke, Lizzy almost got in the way of her big sisters solving the mystery in "The Case of Thorn Mansion." Jay Leno shares the clip.
Lizzy also recalls her family's no-so-good-luck with childhood houses in the San Fernando Valley -- eeek!
