Paranormal activity ?

So i watched the film for the first time after seeing it in the cinema, and was wondering:
The film didnt have credits, even though the people were actors ?
And in the film the actors use their real names, so did they actually experience paranormal activity ?
And is paranormal activity one and two based on real events ?

Yeah they were actors. I saw an interview on the girl after the movie was made. She said she made so little money on the movie she only bought a handbag she wanted. Seriously. lol. I think they MIGHT be based on real events. I mean maybe possibly something like that has happened before. They are so many people and weird things in the world that Im sure it may have happened to somebody.

Well this movies is one of the best scary movie of the year and I think It is based on a true story.That is why? this movie was choosed as a best movie in the cannas and It is said that Paranormal activity 2 is even thrilling and scary that the first part.You will get goose bumbs on you.|||i always heard that the first one was a college project and it was not real, it seemed way to fake. But i cant say about the second one my brother in law went to see it and said it did seem like it was real, so its possible the first one was just to see home much revenue they could get and the second maybe the producers decided to do an actual paranormal story. but i guess the only way to know for sure is go to a search engine and type in this question it this question and it will give you the info on it.|||no they didnt.
they are actors.|||Ya that is based on real events.
