Man, every time I pop on 'Scooby-Doo 2: Monsters Unleashed' I grin at how familiar the faces are. The big ones who definitely returned from the first movie are the Mystery, Inc. crew: Freddie Prinze Jr. as Fred, Sarah Michelle Gellar as Daphne, Matthew Lillard as Shaggy, and Linda Cardellini as Velma. And of course Scooby-Doo himself is back, voiced by Neil Fanning.
Beyond the core team, Rowan Atkinson also shows up again, keeping that cheeky vibe in the supporting cast. The film leans on that continuity to let you settle right back into the gang’s dynamics, so if you enjoyed the first movie’s chemistry, the sequel keeps it intact and cranks the monster dial up. I still laugh at the little callbacks between Fred and Shaggy every time.
