With so many Americans glued to their TVs on Friday night, box office numbers were slightly lower than anticipated this weekend. Still, Oblivion managed to open with a $38.2 domestic haul. (The sci-fi Tom Cruise vehicle has now earned a total of $150.2 million worldwide, having had its $61 million overseas debut last weekend.) Coming in at a far second was Jackie Robinson biopic 42, which earned $17.6 million over its sophomore weekend, bringing its total haul to about $54 million. The Croods continued its slouching success with third place earnings of $9.7 million, bringing its five-week total to $155.2 million. Scary Movie 5 and GI Joe: Retaliation rounded out the top five with a less-than-spectacular $5.89 and $5.7 million, respectively — though GI Joe's month-long loot now totals $111.2 million.
