It was a slow weekend at the box office, but "Teenage Mutant Ninja Turtles" showed it has some fight left, passing the $300 million mark worldwide. Domestically, the film finished second overall, picking up an estimated $6.5 million according to Box Office Mojo. Of "TMNT's" $300 million, more than $125 million has been earned overseas.

"Guardians of the Galaxy," in its sixth weekend of release, again conquered with $10.2 million -- but even that was the lowest first-place finish of the year, as reported by Variety. Marvel's cosmic adventurers have earned $294.6M domestically -- the year's highest so far -- and $291.6M in overseas numbers, for a combined $586.2 million.

By comparison, "Guardians" passed the $400 million worldwide mark in its third weekend. The "Ninja Turtles" hit $300 million in its fifth. Box Office Mojo reported that this was the lowest-grossing box office weekend in two years.

The total haul for the newest, Michael Bay-produced iteration of the heroes in a half-shell puts the film at 16th place on the 2014 global market, behind "Lucy," the Luc Besson-directed, Scarlett Johansson sci-fi action flick. "Transformers: Age of Extinction," directed by Bay, is still the highest performer of the year and the only 2014 film to crack $1 billion worldwide gross.
