The sixth Harry Potter film - I don't like my performance in that film at all.

I get constantly mistaken for Elijah Wood. I was in Japan and someone held out a photo of him for me to sign.

When I get into trouble at school I'd like to take an invisibility cloak, drape it over me and sneak out the door. Or I'd like to have a 3 headed-dog because then no one would argue with me.

I have described myself as being 'gently eccentric.'

The best thing I've learned is, if you're going out, never go out alone - you leave yourself vulnerable. If you've got someone else there you trust, they can say, be wary of that person. I probably used to be too trusting of people.

My mom and dad were actors when they were younger and had a horrible experience of it. My dad became a literary agent and my mom a casting director.

Every day I would come to set [of Swiss Army Man] going like, "How are we going to do this?".
