Harry Potter [1] is the franchise that keeps enduring, particularly right now — there are new book covers coming out [2], a new spinoff trilogy [3] in the works, and this week, another Wizarding World of Harry Potter [4] theme park opens at Universal Studios Hollywood. For the big opening, I was on the red carpet to catch up with cast members Tom Felton, Evanna Lynch, Warwick Davis, and James and Oliver Phelps, and they each dropped a nostalgia bomb when they talked about the movie lines that still resonate with them — for better or worse. Get their favorite quotes, plus what the new Harry Potter ride is really like [5]!
