Thanks to SnitchSeeker we have a lot of fun photos and information from the Harry Potter: The Exhibit press event that was held today.  Head over to the Lewis Lovers gallery to see photos of Matthew at the event!  Matt said the following at the event:

I was stunned. I’d heard about the exhibit in Chicago, but I had no idea about the size and scale. It was incredible and it was really wind-y and mazelike. You turn a corner and don’t know what to expect. It took me back to Leavesden when I was 11 and you’d walk into the Great Hall or Chamber of Secrets – it reminded me of that. When the door first opens and the Hogwarts Express is there – the kids’ll love it! What I hope is that they get to experience a little bit of what we do there (on set).

He also talked a bit about Deathly Hallows:

I got the script – fourth draft – of Part Two and I’ve no idea how we’re gonna do it. The scale of it is enormous. We’ve got some pretty incredible scenes to shoot.

I start next week. Neville is a bloody and battered resistance leader – a battle hardened veteran. A bit gung ho.

Also according to this article:

“I’ve definitely grown up with Neville, grown in confidence and maturity as the character has,” he said.

Lewis was 11 years old when he started playing Neville in the first Potter film. He’s now 20, and about to begin filming the final chapter in the series. When asked if he will miss playing Neville he said, “Absolutely, Neville’s been a huge part of my life. And not just the character, all the people, the studio, the cast and crew, that sort of safety net of Harry Potter really. It’s been a magical world I’ve been a part of.”
