Linda Cardellini, who provided the voice for Hot Dog Water, Velma's science fair rival, also portrayed Velma in Scooby-Doo (2002) and Scooby-Doo 2: Monsters Unleashed (2004), which were also Matthew Lillard's first outings as Shaggy. She reprised the role of Velma in a few episodes of Robot Chicken (2001) some years later.
