Welcome back, Sandra Bullock! The Proposal accepted $34.1 million in ticket sales, giving America’s Sweetheart the No. 1 movie at the box office, and simultaneously knocking The Hangover into second place. The celebration wasn’t as joyous for Year One though, as the prehistoric comedy landed in a disappointing fourth with a pedestrian $20.2 million. As we do each Monday, here’s a breakdown of the top five at the box office.

1. The Proposal: $34.1 million ($34.1 million total)

File this under: If you build it, they will come. The Proposal is the first star-driven romantic comedy to hit theaters since Ghosts of Girlfriends Past on May 1 and it clearly filled a major void in the summer marketplace; 71 percent of the audience classified themselves as “couples.” For Ms. Bullock, in addition to being the biggest opening of her career, The Proposal marks the first time she’s seen one of her films top the box office since Forces of Nature turned the trick in the spring of 1999. At a time when A-list stars are watching their films fall by the wayside, watch Sandy rising! Now the mysterious  All About Steve, co-starring the now A-listed Bradley Cooper and reshuffled till September,  looks like a potential winner.

2. The Hangover: $26.8 million ($152.9 million total)

Somebody call 911. The Hangover continued its fire-burning run, dropping a laughably low 19 percent over the weekend, en route to bringing its total to nearly $153 million. Forget just passing Wedding Crashers as the highest grossing R-rated comedy of all time; Todd Phillips’ smash could wind up as the third-highest-grossing R-rated movie ever, behind only Matrix Reloaded and The Passion of the Christ. Not bad for a “sleeper hit,” eh?

3. Up: $21.3 million ($224.1 million total)

By shedding only 31 percent of its audience from week-to-week, Up continued its rise on the Pixar charts, passing Wall*E to land in seventh place all-time for the studio. With $224.1 million to date, Up will easily glide by Cars, Toy Story 2 and Monsters, Inc. in the coming week and it should still cross the $300 million barrier before all is said and done. And to think, the Wall Street types were worried about this film just two months ago.

4. Year One: $20.2 million ($20.2 million total)

Easily one of the worst movies of the year, Year One barely topped the opening of Land of the Lost to wind up in fourth place over the weekend. Since Year One cost about half as much as Will Ferrell’s bomb, the losses won’t be as severe, but, with word of mouth sure to be poisonous, don’t expect final grosses much more than double this opening haul. If this is the best Harold Ramis can come up with, we weep for Ghostbusters 3.

5. The Taking of Pelham 1 2 3: $11.3 million ($43.3 million total)

The Taking of Pelham 1 2 3 plunged 51 percent from last week, but still managed to hold off the fifth frame of Night at the Museum: Battle of the Smithsonian ($7.3 million/$155.9 million total) to land in fifth place. We’re not saying that level of attrition isn’t disappointing, but with everyone touting Pelham as a failure, we must again note that a final tally of around $70 million will be right in line with the average grosses of Denzel Washington ($70.7 million) and John Travolta ($62 million) since 2000. What did everyone expect here? Sometimes the reality trumps perception.
