Friday Oopsing

Well, i managed to know when it was the beginning of the week and the beginning of the month, but seemed to have missed the end of the week. Only a few hours left now to squeeze in

So complete was my unawareness that there's nothing ready to go. So you get an off-the-top-of-the-head quizzy sort of Oddity.
Identify these popular stories, all of which have the subject of at least one film...   No, all have had at least 2 or 3 films, if not more.

1) After his wife is brutally murdered by a serial killer, a father must track his now disabled son thousands of miles to rescue him with the aid of a mentally disabled woman.

2) A 17 year old boy starts an illicit 3 day fling with a 13 year old girl, resulting in a half dozen deaths.

3) Two women try to kill each other over a pair of shoes.

4) Mary had a little Lamb.

5) A south-Pacific native finds himself unwillingly in New York City, but still manages to visit the Empire State Building like typical tourists.

what? You wanted pictures? (eep!)
