My life: Sam Neill

I was born in Northern Ireland (where his father, a New Zealander serving with the Irish Guards, was stationed). We worked out that my family has been in the wine business for 150 years, although I'm the first to grow wines. It could be longer, but my great-grandfather, who left Ireland (for New Zealand) in 1860 and was the son of a wine merchant, was unable to verify whether (his grandfather) was also a wine merchant. We've had at least four generations in wine - it was called Neill and Company, back in New Zealand.

I got into acting by accident. I wanted to act but there were no drama schools where I was, so I got into films, but behind the camera. Then people started to ask me to be in their films and I was silly enough to accept the low wages. I'm self-taught, never went to acting school. But I go to acting schools now and pass on what little I know to young people. I was doing a film with Meryl Streep - it was A Cry in the Dark. I asked her if there was a little signature she puts in every film, and she said, "Yes, I always fall over once." She asked me what mine was, and I said, "I always do a 360-degree turn somewhere." That's my signature.

None of my children are actors, although a couple of them could be - they're really good. They don't seem to think that what I'm doing is a real job. Recently, I've been extremely busy. I finished Alcatraz (last) February and did two other television programmes; one was called Harry, the other Peaky Blinders. And I've done two movies: A Long Way Down with Pierce Brosnan and Toni Collette, and The Tomb, with Sylvester Stallone and Arnold Schwarzenegger.

Making good films and good wines are both very difficult to do. Both are expensive. You need an excellent team and a lot of commitment, and a tremendous amount of profound knowledge. And if they're to be any good, they should be made with a lot of love. I think love is the most important thing of all. There's a lot that goes into both that the end user doesn't see. For instance, if you're doing an action film, you would think it would be pish-posh, but making an action film is the slowest, dullest thing. You need hundreds and hundreds of people to do dull little jobs, and the whole thing (on screen) is over in 10 seconds. With a great bottle of wine, those vines have been nurtured and tended and cherished for years and years.

When I was growing up, there was always wine in the house, but it wasn't until I was 29 that I actually had a glass that made me realise that wine is fascinating and splendid and multilayered, and something akin to poetry. It was in Switzerland, and I was staying with (actor) James Mason and his wife. James brought a bottle of burgundy to a restaurant. It was a bit of a revelation to me. When I went back to London, I started following burgundy - starting with white burgundy, then that morphed into an interest in reds, which, of course, are made of pinot noir.

I'd built my house with the idea that we would settle back in New Zealand, but it just happened to also be the right place for wines. There was a man named Rolfe Mills, of Rippon Vineyard - he died some years ago and his son runs the winery now. Rolfe was an old family friend of my father. He had started to produce some really interesting pinot noirs and it was drinking his wine that made me want to do this. In 1992, we started planting our first vines. At that stage, I think there were three little wineries in Central Otago, but now it's something like 200. I'm the only person at (Neill's vineyard) Two Paddocks who doesn't get paid. It sustains itself but it doesn't pay me.
