Unlike economics, whose sole preoccupation in our finance-obsessed era is the near-term profit motive, history offers a way to place our tiny lifespans in a narrative that spans dozens of generations - perhaps even reaching into a future where capitalism is no longer our dominant form of economic organization.

We can celebrate how far we've come from our sexist past when women and men are equally represented in the pages of science fiction anthologies.

Interstellar' is a thematic sequel to Christopher Nolan's last original film, 'Inception'. It drops us into a dark future full of otherworldly landscapes and time distortions.

Fifty years ago, historians advised politicians and policy-makers. They helped chart the future of nations by helping leaders learn from past mistakes in history. But then something changed, and we began making decisions based on economic principles rather than historical ones. The results were catastrophic.

When I won the Oscar, I fell into that mind-set that this is a precious role. People everywhere were shouting, 'Show me the money!' I just didn't want anything that could parody the fact that I was like a tagline in a movie. So when Steven Spielberg offered me 'Amistad,' I said no; when 'Hotel Rwanda' came along, I said no.

That's the principal guiding feature of all interviews today is money.

The rules of game shows limit stuff so much. I remember on 'Money From Strangers,' being in the van - not even performing - and there was a lawyer there the entire time. 'No, you can't give money for that. Yes, you can give money for that. That's a partial answer. That's a full answer.'

For me, a good holiday is about value for money rather than things to see.
