Unless it's an animated film, I don't see that happening. If it only grossed 19M, then 60M might not be happening. And I'm not sure if you know this, but it is a PG-13 movie. Not exactly a “family” movie. Try to be logical at least.
Hunger Game had great WOM, and look at the 2nd weekend drop, almost the exact same as SM3. It all depends on how big the movie opens in the first weekend.
Early world for Les Mis was mixed as well, look it how well that turned out! If Les Mis can gross 148M domestically, Great Gatsby will have no problem crossing 100M+.
