Holdovers led the charge this weekend at the domestic box office, as nationwide newcomers "Rock of Ages" and "That's My Boy" fell flat. Warner Bros.' rock-music ensembler earned an estimated $15 million through Sunday, while Sony's latest Adam Sandler pic came in with $13 million. Both debut perfs were on the low-side of modest pre-weekend expectations. Winning the world for its second straight frame, "Madagascar 3: Europe's Most Wanted," from Paramount and DreamWorks Animation, added another chart-topping estimated $35.5 million to its $120.5 million Stateside cume. Toon estimated $53 million internationally this weekend, yielding a overseas tally of $157 million for $277.5 million globally. Fox's "Prometheus," meanwhile, fell 60% domestically -- slightly steeper than expected -- for an estimated soph-sesh take of $20.2 million, which brings its domestic cume to $88.9 million. Last weekend, "Madagascar" and "Prometheus" helped Stateside box office eclipse 2011's running summer tally by 2%; that lead likely won't last through the weekend. "Rock of Ages," budgeted at $75 million (not including marketing), and "That's My Boy," which cost $65 million, weren't expected to blow away the competish, though neither opening gives much momentum for the pair over the long haul. "Rock of Ages" received a soft B CinemaScore rating; "That's My Boy" scored a B- overall. Warner prexy of domestic distribution Dan Fellman noted, however, that "Rock" could benefit from targeting a mostly over-25 female crowd. "Female-skewing movies tend to play better mid-week," Fellman said. "So we'll see if we can play a little catch-up." Playability is stellar for some pics on the indie front; most notably, with Focus Features' "Moonrise Kingdom," which grossed $2.2 million from 178 locations. Pic's cumed $6.8 million after four weeks domestically.
