The most challenging scene for me was the spider scene, because I don't like spiders in real life. Even rubber ones I get really scared of.

I get recognised sometimes, and that's really cool. I've tried certain disguises, but that doesn't work.

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'd like to levitate.

There's a bit of pressure when you're reimagining something so iconic and loved. But the only way you can really do it is completely reinvent it.

There's a real sense of freedom now. It's a good time to finish, I think. As much as I'm going to miss it I'm ready to move on and do different things.

Every time I come off-set, I am just like a normal kid again.
