ABBA: The Movie; I got a lot of grief for working on that.

I made all their videos, apart from the last two, so if you ever see an Abba video on TV then it's my stuff.

I got to work with my wife, Lena Olin, for the first time, which was great. I thought it might be difficult in some way to talk to one's wife in a different way but it was so not forced.

It's a farce, it's a romp, it's a glass of champagne, ... It's whatever you need for the moment. I enjoyed my half-year working on it, and I hope that joy that we experienced will be reflected a little on the screen.

I imagined that it might be awkward to talk to your wife about her performance, so going into it I was a little nervous. But doing it was actually a wonderfully inspiring experience.

I'm on this diet where you're supposed to eat only fish and meat.
