I heard that the same thing occurred in a scene in Alien, where the creature pops out of the chest of a crewman. The other actors didn't know what was to happen; the director wanted to get true surprise.

This is a tricky domain because, unlike simple arithmetic, to solve a calculus problem - and in particular to perform integration - you have to be smart about which integration technique should be used: integration by partial fractions, integration by parts, and so on.

If you just have a single problem to solve, then fine, go ahead and use a neural network. But if you want to do science and understand how to choose architectures, or how to go to a new problem, you have to understand what different architectures can and cannot do.

There was a failure to recognize the deep problems in AI; for instance, those captured in Blocks World. The people building physical robots learned nothing.

There are three basic approaches to AI: Case-based, rule-based, and connectionist reasoning.

We wanted to solve robot problems and needed some vision, action, reasoning, planning, and so forth. We even used some structural learning, such as was being explored by Patrick Winston.

Once when I was standing at the base, they started rotating the set and a big, heavy wrench fell down from the 12 o'clock position of the set, and got buried in the ground a few feet from me. I could have been killed!

In general we are least aware of what our minds do best.

By the way, it was his simulations that helped out in Jurassic Park - without them, there would have been only a few dinosaurs. Based on his techniques, Industrial Light and Magic could make whole herds of dinosaurs race across the screen.

The basic idea in case-based, or CBR, is that the program has stored problems and solutions. Then, when a new problem comes up, the program tries to find a similar problem in its database by finding analogous aspects between the problems.

No computer has ever been designed that is ever aware of what it's doing; but most of the time, we aren't either.

When David Marr at MIT moved into computer vision, he generated a lot of excitement, but he hit up against the problem of knowledge representation; he had no good representations for knowledge in his vision systems.

You don't understand anything until you learn it more than one way.

I think Lenat is headed in the right direction, but someone needs to include a knowledge base about learning.

Around 1967 Dan Bobrow wrote a program to do algebra problems based on symbols rather than numbers.

Societies need rules that make no sense for individuals. For example, it makes no difference whether a single car drives on the left or on the right. But it makes all the difference when there are many cars!

Kubrick's vision seemed to be that humans are doomed, whereas Clarke's is that humans are moving on to a better stage of evolution.

Stanley Kubrick knew we had good graphics around MIT and came to my lab to find out how to do it. We had some really good stuff. I was very impressed with Kubrick; he knew all the graphics work I had ever heard of, and probably more.

I believed in realism, as summarized by John McCarthy's comment to the effect that if we worked really hard, we'd have an intelligent system in from four to four hundred years.

Artificial intelligence is the science of making machines do things that would require intelligence if done by men.

Actors love mental disorders, dialects, and corsets. Give them one of the three and they're happy.

What's fascinating is that when you write a script, it's almost a stream of consciousness. You have an idea that it means something, but you're not always sure what. Then when you get on the set, the actors teach you.

Young actors often don't think of the consequences of doing nudity or sex scenes. They want the role so badly that they agree to be exploited, and then end up embarrassing family, friends, and even strangers.

I've seen many actors go awry by making the wrong choices early on.

Actors are able to trick themselves into treating anything as if it's fantastic. It's a kind of madness really.

David Cronenberg knows what we actors do as artists.

I like doing them and they're ridiculous and the actors can improvise a lot, and they don't have to be really realistic characters that hit a very specific tone as in a feature film. They're really fun, I want to make more of them definitely.

I'm not in the business of becoming famous. And that's the advice I give to younger aspiring actors. Work onstage and do the little roles. In the end it's not important to be seen. It's important to do. There's a lot of disappointment in this business, but my family keeps me grounded.

Actors get pigeonholed very quickly, particularly movie actors. In the theater, one is more used to casting people against type and trusting that their talent and skill will get them through.

Comedians are not usually actors, but imitations of actors.

I was very pleased you know, and I was afraid that I might stick out, but I didn't. My happiest thing about that picture is that I proved that American actors can speak as well and also fit in with an ensemble like that.

I've worked with a lot of really fine actors, both on stage and on screen. The level of their game lifts me up and brings the level of my game up to theirs. Always. It's like a constant upgrade.

I feel like I'm the most well-adjusted character on the show, even though I'm sure the other actors would tell you the same thing about their characters.

There's a constant flow of child actors. It's kind of funny to watch the new crew come through. I think, You poor little things. You're going to have to struggle for a long time.

I'll miss the relationships I have built with these actors. I'll miss the devotion we have to this work. Over this length of time, the tendency is to think it will never end.

After the war, there was no industry. We lost the war. We had our whole city destroyed. No money. No studio. No film. No camera. No equipment. We would shoot in the street. We had no actors. Nothing. But we wanted to do movies. And we did the best movies in the world.

An actors' tribute to me is in his work.

A few nights ago I went to a Hollywood screening of a small independent film made by Sally Kirkland, an old friend of mine who also did terrific job acting in it. There were other actors in it and they were all terrific.

This friend of mine said he was surprised to find that - I don't think it's quite a majority - a bigger percentage of actors are introverts than extroverts. It was a big surprise to him. Now, I know me, and I'll do anything if I'm playing a character. Or anything that's true to the character, anyway. But in real life I'm a little more withdrawn.

Plastic surgery and breast implants are fine for people who want that, if it makes them feel better about who they are. But, it makes these people, actors especially, fantasy figures for a fantasy world. Acting is about being real being honest.

When on the set of a film, you have to play natural for entire scenes in a very unnatural environment. You have to express emotions and interact with other actors and also use your voice.

If you watch the show and the characters don't look at each other while they're talking, the actors probably aren't getting along.

When I decided I wanted to be an actor, I said I wanted to work with quality actors and directors.

My favorite actors when I was a kid were in their '60s. Spencer Tracy, Humphrey Bogart, John Wayne.

I think it's hard to know. Feeling fulfilled, because actors face periods of unemployment, there is nothing worse than being at the top of your game; you have so much to give but do not have the platform to do this.

I usually hang out on the set. I get to know everybody. I have a nice time with the other actors.

But what I did think would be interesting is if we created a fictitious story of our own, and then took these stories that we had collected and assigned them to characters who would be played by actors.

Actors are an insecure breed. It's hard to have your career depend upon other people's opinions of what you do.
