I think coughing up slugs was quite hard. Ron has a scene where he has to cough up these giant slugs.

I had this giant slug in my mouth loaded with slime and I spat them out. I think it was plastic. I hope it was plastic.

I'm shorter, I don't have as many freckles as Ron, and I can't do magic.

I was always a big fan of the books and over the years I've become quite attached to Ron and we've meshed into the same person, really.

We just started filming, and after every scene was shot, we had a rehearsal for the next one.

Ron was always my favorite character, because I feel like I relate to him, like we've both got red hair, we both like sweets, we've both got lots of brothers and sisters.
