One time we stayed at a B&B, and there were a couple of hippies who had this nice little area and they let us sleep in their beds that they had in the back.Then the woman suggested we go out and lie on some cushions and look up at the stars and look for UFOs and she said, "You know, I do this all the time," and I was like, "Okay..." So there we are, lying there next to this amazing loch, and we're looking up in the stars and I don't really know what I was expecting, but to see some sort of metallic object.

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 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.

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.

Luckily the script [of X-files episode] was written wonderfully and that became who I was and I was quirky, and I was kind of agitated and not entirely happy, but at the same time, witty.
