Character Role Analysis
Tom Riddle
This is a tricky one because no one—not even Harry—realizes that Tom is the bad guy until the very end of the movie. When Harry first sees Tom Riddle in the Chamber of Secrets, he still thinks the Slytherin prefect might help him rescue Ginny.
Nope.
Then Tom reveals that he's actually a young Voldemort and we're super shocked. This is the worst kind of villain. The one you think you can trust…until he sics a giant, murderous snake on you. Not cool.
