Thought she look familiar

Was googling some of the cast names of 'Freaks and Geeks' at Yahoo.
Came across several surprises.
Like how the cast appear/look at present time.
And how much have they changed.
For example, Linda Cardellini (second from the extreme left)
She was a cast in the 'Scooby Doo The Movie', as Velma.
Now, that solve the puzzle, why she actually looks familiar.
