Extraordinary claims require extraordinary evidence, and it is my job, my responsibility, as an astronomer to remind people that alien hypotheses should always be a last resort.

'Alien' asked ground-breaking questions about eco-politics and female empowerment. 'The Matrix' delved deeper into the concept of perception versus reality than perhaps any other film I know. But for some reason, we tend not to remember the significance of their writing.

I think obviously there is some kind of life form somewhere else. Whether it looks like the creature in 'Alien Autopsy,' I'm not sure.

Part of the reason why Scandinavian crime has been so popular is the landscape. It is just so strong and alien. Although without taking anything away, you should probably also never discount the fact that blood does look particularly good against snow.

I remember as a child going to an exhibit about the Soviet Union, and every paper had this alien smell. The paper and the ink were all exported. It was like a piece of cheese from that country, you could touch it, feel it, smell it, and it was different.

I was very affected as a foreigner coming from Copenhagen, which is the safest, most liberal town in the entire galaxy. I was like an alien stranded in a strange land for the first time in the U.S.

It was 'ST' format to let space and alien worlds, rather than human weakness, provide the conflict and danger necessary to our adventure show.

The first time I saw E.T., the actual image of an alien, and he was so sweet-looking. I wanted him. I wanted E.T.

I always felt that if we ever encountered an alien species, they wouldn't look like us or even be humanoid, like 'E.T.'

'Alien?' Oh, yeah. I still get fanmail almost every week, pictures from all over the world on that movie. That's one of the most popular films I've done.

How do you live with one person for 13 years and another for eight and find both as alien as strangers?

I've been stealing from the Alien films throughout my entire career.

I feel trapped in my body. I want to be like like Scarlett Johansson in 'Lucy,' when she unlocks everything within her - I want to do that. I want to be the alien in 'Arrival' - a spitty, infinite-time-loop creature.

Honey, I beat down an alien with my purse in the 'X Files.'

If an alien race lands on the planet Earth tomorrow and asks me to prove I'm really here, what do I do? What do I give them? What do I tell them? What do I show them? I can't sing or dance. I can't paint. I've never built anything, and I've never contributed anything significant to the human race.

Playing an alien gave me plenty of scope, and I was able to develop it once I became a member of the team.

You can't put abandonment and alienation under arrest.

We do stigmatise teens a lot and see them as scary and alien.

I did not want 'Battleship' to be perceived as an American war film. I wanted to do everything I could to make the film accessible to a global audience. It felt like bringing an alien component to the film would help take the American jingoism out of it.
