Every actor knows for sure that if you have ever starred in a sequel you will most probably be associated with the hero you played till you die. Yes, most of us still call Johnny Depp Jack Sparrow, Leonardo di Caprio - Jack from "The Titanic" and Renee Zellweger as Bridget Jones. And the same thing happed to the cast of "Harry Potter" films - no matter what heroes they play we will always remember them as Harry, Hermione and Ron. And this hilarious trailet is another proof that makes our words trustworthy because Harry Potter fans will never forget!
