What should I do? Please help!?

Okay, it's kind of hard to explain. But here it goes:
Yesterday a guy on Facebook friended me. His name was Aliex. I saw that we had some mutual friends, and he lived in my hometown, so I figured, "Hey, I probably know him". So I confirmed the request.
Well, earlier today, he messaged me. I'm just going to copy and paste the conversation.

Aliex (A): Hey gergous
Me (Me): Hey (:
A: how r u doing
Me: good just bored :\
how bout you?
A: Good boo damn girl
Me: haha so have we met before?
A: na i don't think so
But i would really like to get to know ya
Me: cool. what do you want to know about me?
A: Do you like movies . If so what is your favorite
everything
Me: yeah, i love movies. my fave of all time would have to be Soul Surfer.
you?
A: i adore movies my favorite is scream orignal
Me: sorry gtg
byeee ttyl
A: kk gergous cant wait

Now, when he started all that flirting stuff, I was just like "Okkieee-dokkieeee.... Anyways.." I figured it wasn't that big a deal. I thought he might've just acted like that around all girls.
Then, when he said his favorite movie was Scream, I looked it up real quick.
Here's the plot (from Wikipedia):
High school student Casey Becker receives a flirtatious phone call from an unknown person, asking her, "What's your favorite scary movie?" The situation quickly escalates out of control as the caller turns sadistic and threatens her life.
I didn't copy the whole thing, but when I saw that, I decided to leave, because of how oddly familiar the situations were, and I reported him a couple times, but I didn't block him, in case I needed to see his profile again.

Please help. I don't know what to do. Is this just a coincidence? A prank? Is my life in danger? What do I do?

If you feel threatened, by all means, unfriend him, report him and block him.
