Wither as a Movie?

I had brunch with a friend of mine the other day, and as we were catching up, we started talking about movies we were both looking forward to (The Help and One Day, to name a few) and she mentioned a movie I had never heard of before starring Justin Timberlake.

"It's so cool!" she said. "It takes place in the future, and everyone dies at 25."

Cool idea, I thought to myself. But it sounded a little familiar...where had I heard that before...

"And there's these rich people, who, like have lots of wives and try to live forever."

Sure, she wasn't being super specific, but I had to jump in because I was excited. I had totally read this book!

"Are you talking about Wither? They're making that into a movie already?"

It seemed to fit--people dying at the age 0f 25, multiple wives, rich people...I mean, Hollywood wouldn't rip off ideas that blatantly would they?

She looked at me, a little confused. "I don't know. It's called something with "time." And it has Justin Timberlake." (She really likes Justin Timberlake)

Well, it turns out that she was not talking about a movie adaptation of Wither, but the movie In Time, that comes out on October 28, 2011.

After watching the trailer, I don't think it looks like a rip-off of Wither, even though they do share some similarities. (Oh, and I'm not sure where she got the multiple wives part...I didn't see that in the trailer.) It also reminds me a little bit of the premise of Numbers (or Num8ers), but I haven't actually read Numbers, so I can't really say.

What do you guys think of the trailer? Does it remind you of any books you've read recently?
