Why The “Curious” Case of Benjamin Button?

First of all The Curious Case of Benjamin Button is such a beautiful movie.  The Set. The Story. The Characters.  The actors, particularly, Brad Pitt. He’s beautiful in this movie – the way he looks and his superb acting.

Watched the movie last night at Glorietta 4 with my girlfriend, Picci.

But ever wondered why the title used “curious” to describe the case of Benjamin Button? Why not use “weird” or some other adjective?

So I checked the dictionary and found out that the word “curious” has 3 meanings:

1. a archaic : made carefully b obsolete : abstruse carchaic : precisely accurate
2. a: marked by desire to investigate and learn b: marked by inquisitive interest in others’ concerns : nosy
3. : exciting attention as strange, novel, or unexpected : odd <a curious coincidence>

I only knew of the 2nd meaning until i checked recently.  Obviously the movie title intented to use the 3rd meaning. The Strange / Unexpected / Odd Case of Benjamin Button.
