However, one show we absolutely fell in love with was "The Secret World of Alex Mack." For those that don't remember, 'The Secret World' followed Alex Mack, a junior-high student who was splashed with a chemical experiment during class, resulting in secret powers. The series only ran from 1994 to 1998, but clearly cemented a place in our hearts.
Along with those amazing projects, you also may also notice Oleynik as Maggie Cutler in "Pretty Little Liars," or even Cynthia Cosgrove in "Mad Men."
According to her IMDb page, the 35-year-old actress is is still keeping her stride with previous TV movie "Wish Upon a Christmas," and upcoming film, "Animal Among Us."
Needless to say, Larisa is just adorable and beautiful as she was back in the 90s!
