( Entertainment Weekly ) -- Sandra Bullock will surely be popping open the champagne as her new romantic comedy , `` The Proposal , '' accepted the top spot at the box office this weekend by grossing $ 34.1 million , according to early estimates by Hollywood.com Box Office . Ryan Reynolds and Sandra Bullock have reason to celebrate after `` The Proposal '' takes top box office spot . Not only did `` The Proposal '' win the weekend , but it was by far the best opening of Bullock 's career , nearly doubling the opening of her previous best , `` Premonition , '' which debuted to $ 17.6 million in 2007 . While `` The Proposal 's '' success was fueled mostly by women ( 73 percent of the audience was female ) , both women and men gave it a healthy `` A- '' CinemaScore rating , so expect the movie to hold up fairly well during the next few weeks . The weekend 's other big release , the prehistoric buddy comedy `` Year One , '' landed in fourth place with $ 20.2 million -- an okay debut for the $ 60 million movie . However , all indicators point to a quick descent for the Jack Black/Michael Cera flick . `` Year One '' dropped 24 percent from Friday to Saturday ( never a reassuring sign ) , and the movie received an unimpressive `` B- '' rating from CinemaScore . `` Year One '' is all but certain to join `` Land of the Lost '' as another box-office disappointment for high-concept comedies . On the other hand , `` The Hangover '' ( No . 2 with $ 26.9 million ) and `` Up '' ( No . 3 with $ 21.3 million ) continued to show off their box-office stamina , dropping only 18 percent and 31 percent , respectively , from the prior weekend . `` Up '' now stands at $ 224 million , and may levitate past `` Star Trek '' ( currently at $ 239 million ) to become the year 's highest-grossing film . Finishing off the top five was `` The Taking of Pelham 1 2 3 , '' which fell an alarming 52 percent for an $ 11.3 million weekend stash . Also opening this weekend was Woody Allen 's `` Whatever Works , '' starring Larry David . The New York-based comedy laughed up $ 281,000 from just nine theaters for a weekend-leading $ 31,000 gross per theater . The film will expand to more than 300 theaters on July 3 . Overall , the box office was up 3 percent compared to last year 's Father 's Day weekend , when `` Get Smart '' debuted to a surprisingly sharp $ 38.7 million . Hope you all are having a splendid Father 's Day ! I know I will -- I 'm taking my pop to see `` Up . '' CLICK HERE to Try 2 RISK FREE issues of Entertainment Weekly .
