SCARLETT JOHANSSON beat THE ROCK at the box office this weekend, by a pretty wide margin. “Lucy” brought in a better-than-expected $44 million, compared to just $29 million for “Hercules”. It’s even more impressive when you consider the budget for the two movies: “Lucy” cost an estimated $40 million to make, which means it’s already made back its entire budget . . . while “Hercules” cost $100 million, so it hasn’t even made a third of that yet.

1. NEW: “Lucy”, $44 million.
