On June 13, 1986, the world was introduced to two pint-sized stars in the form of Mary-Kate and Ashley Olsen. While the fraternal twins have since moved on to a career in fashion, they made their name as actresses and movie-makers. In the '90s and early '00s, the Olsen twins released various straight-to-VHS and TV movies, always starring the actresses as twins who engage in a multitude of adventures. The movies also served as an early introduction to the world of film for major stars including Megan Fox, Michael Cera, and Jesse Spencer.
