It seems a little skin might just go a long way.

After weeks of talking to the media about their joint nude scene, Sandra Bullock and Ryan Reynolds saw their movie take the top spot. Was it a coincidence? Maybe. Whatever the reason, The Proposal became the actress’ biggest opener ever. Prior to this weekend, 2007’s Premonition - a horrible film, btw - had Bullock’s largest debut. (That movie grossed $17.6 million, almost 1/2 less than the romantic comedy.)

Meanwhile, Reynolds is this week’s Bradley Cooper. Sandra’s leading man, like The Hangover star, has just had his second #1 film of the year. (The first being Wolverine.)

Speaking of the Todd Phillips’ entry, that laugher continues to show strength despite its second place finish. Hangover, earned another $26.7 million this weekend making it the fastest R-rated comedy to ever move past the $150 million mark. The record was previously set by Wedding Crashers, another Cooper movie.
