I went to meet Joe Johnston, the director, and he's charming. I've been very lucky. Most of the directors I've worked with are charming. But Joe's a particularly charming man, and he showed me lots of designs and, rather memorably, welcomed me to the Marvel Universe.

It's always very strange to have your life dramatized because it never happens like that. Things will be different.

Often jobs are un-turndownable even before you read the script. You go, "Well, I have to do that."

We're blessed with, as we were on 'Harry Potter,' lead actors who are amazingly grounded people.

I often get sent scripts about little men in big situations. There's a comic element to it, which is forces stacked against this little guy, and how is he going to defeat them?

Hitchcock is a big ask. I am playing someone significantly older than me and someone significantly bigger than me. The stuff I find very interesting is why certain physical things have come about. How can he be light on his feet when he is so big? How can his weight vary so much? Where does this rather beautiful voice come from?

I've got to tell you, I've played real characters before and people always bring up this word 'impersonation,' and I'm never entirely sure what it means.
