10 Disturbing Movie Reveals You Only Notice Rewatching

While still technically a family film, the late reveal of Scrappy-Doo being the evil pup sitting within a mechanical Emile Mondavarious is still a little disturbing to watch all these years later.

But that hilariously shocking turn of events was actually hinted at a little earlier in the 2002 live-action Scooby Doo madness.

When the Spooky Island owner is spotted wondering what spooked the titular canine after a mid-film piano performance, Mondavarious does something that pretty much gives away the twist there and then.

The way he scratches behind his ear here is pretty similar to the way a dog would do that very same thing.

But when taking in the flick for the first time, you'd be forgiven for thinking Rowan Atkinson's character just had a nervous tic he couldn't control in the moment. And most weren't exactly quick to jump to the conclusion of the little egomaniac, booted out of Mystery Inc. after trying to take over the team, being the one behind the soul-stealing plot on the island.

However, once you learn exactly which irritating pooch was sitting within this villainous bot all along, this initially missed puppy-powered hint sticks out like a Scooby snack in the middle of a bag of chips.
