Best way to get a actors reaction?

[RiseDarthVader]

I'm making a film about invisible aliens attacking my school (I know it sounds cheesy) and I'm directing because I want to make a career out of that. So what is the best way to get a actors reaction from something that really isn't there? Any tips? This is my second film project.

Well if you only have certain people to choose from then theres one thing. I would star with good actors, but if ot. Stay with close ups of reaction shots.

If you have to have a crowd scene, or shots at a distance of what is supposed to be there but isn't then tell them to react to something scary. Let them know something they can put a face too. Be it the Predator to Giant Spiders. Predator is the best. Most people can reference this movie. They'll start looking around and acting like they have the predator. Give a reference though. That is the best advise I can give you if you have just every day people. PM me if you have anything else, but I'm sure we can all help.

Try making the actors feel nervous. Give them as little info and direction as possible. Frustrate them, don't hold their hand. Avoid extensive rehearsals. Don't reveal too much of the script. Make the actors feel very uncomfortable with you, and the whole film. They mustn't enjoy it.
The actors insecurity and frustration will possitivly affect their performance. The stress will show in the scenes. It is ideal for suspense/horror.

If its pain - kick them in the nuts. Then tell them you want them to like like they did when you kicked them in the nuts.
