10 Things We Learned From Universal Orlando's A Celebration Of Harry Potter 2018 Q&As

3. Oliver & James Never Switched Roles

According the brothers, James and Oliver never played each other's characters. They did admit to sitting in each others seats during a test shot for a Great Hall scene, but the pair never appeared on screen in each other's place.

They described it as a cautionary tale as to why you shouldn't believe everything you read on Wikipedia.

The pair were also told by their school drama teacher when selecting their high school classes, "don't bother choosing drama." That teacher is probably regretting that decision now.
