With $52 million, Green Lantern flew into the top spot at the weekend box office, which is what we expected (and predicted) back on Friday. It wasn’t hard to see this coming, though, considering the summer’s other major superhero films (Thor and X-Men: First Class) both opened up at number one, though Green Lantern did earn less than its two predecessors. Meanwhile, the week’s other major release, Mr. Popper’s Penguins, did not have enough to freeze out the competition, despite funnyman Jim Carrey in the lead role. It finished third (behind Super 8) with $18.2 million. X-Men: First Class ($11.5 million) and The Hangover Part II ($9.63 million) rounded out the top five.
