Linda Cardellini as Velma Dinkley
Velma was always the "nerdy" one. Daphne was the "pretty" one. They both filled the stereotypes that they were given (and then some). Linda Cardellini was cast as Velma for the live-action Scooby-Doo films. A lot of people were shocked to see what she really looked like without the horrible wig and glasses!
