This particular one was very, very heartwarming and is the relationship of an older man and a young boy that are essentially on the run. And so yeah, as I say, Barry Crump wrote a lot of books and this one got into the hands of Taika Watiti who then writing the screenplay decided to really vamp up if that's the word, or ramp up and modernize certain phrases - getting in the humor. So he added a lot of a real comedy perspective onto it which is what I think the story needed anyway, especially for it to turn into a film. And it worked.

If you're into comedy, you will know what the show is about. We have so many comedy geeks, comedy enthusiasts, fanatical people who go to comedy festivals and follow comedians, and really treat it like rock 'n' roll - which it can be, but more like the geeky rock 'n' roll.

That's one of the best things about characters like Indiana Jones. I mean, he's funny. He's done really wicked things.

When I did The X-Files, there was certainly less of that because the script was as it was and it was such a wonderful script and it was quite complex and there wasn't a hell of a lot of improvising I could do to bring to the table, but I guess what I did bring was a sense of self and that the reason I was cast was because I did come across as someone who possibly was only human for a short time.

You've got to have a likeability factor, I think, in your comedy characters. If the guy's really, really funny but you just don't like him or her, then you're never going to root for them.

I've never really been into ghosts or spirits, and I've only had a couple of those kind of experiences.

I've always been a big fan of the Yeti, simply because I have an affiliation to Everest - who was the New Zealander, Sir Edmund Hillary, the guy that conquered it.
