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

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. He actually went on an expedition after the Everest climb to look for the Yeti, and they didn't find it, but they found a footprint and some hair samples that turned out to be a goat or something.

['Dad's Army' show]was a military thing but also very funny, so it's kind of the two things that I experienced by being a soldier, and I found it very humorous then and there, because of the juxtapositions [and] me and my emotional state.

I get them [auditions] from time to time, and I sometimes get auditions for big dramas, and I often think, well, I'm not going to get that part. This was a big surprise - it was The X-Files.

I think I can relate to this guy [Psycho Sam] that ended up... This desire to go off the grid and live on his own and didn't trust anyone or anything and I guess the thing that saved him in my head was that he had a great sense of humor.

He [Taika Watiti] worked on this screenplay for a couple of years and just getting it right and the result is there. He's made really close to a perfect film [Hunt for the Wilderpeople]... Perfect as you can be.

When there's characters out there that don't have humor, I don't find them as believable, because we all have humor, no matter what level it is, we all use it every day, no matter what situation we're in, we'll try and have a bit of a laugh even if it goes wrong.
