Oblivion blew away the competition in it's opening weekend (though there were no other big movies opening), brining in $38.2 million domestically and $112 million worldwide in two weeks. The movie marks Cruise's best North American opening outside of the Mission: Impossible franchise and War of the Worlds, not accounting for inflation of course. 

42 continued to show strong numbers despite, in my humble opinion, being a rather weak movie. It declined 34% this week to come in No. 2 with $18 million. The baseball drama's 10-day domestic total is $54.1 million.

Scary Movie 5 placed No. 4 in its second weekend, dipping 56% to $6.3 million for a domestic total of $22.9 million.
