"But what about the 'Sex and the City' movie?" you may ask yourself in reference to last year’s hugely successful big screen debut of the Big Apple’s fabulous foursome. Well, the "Sex and the City: The Movie" went on to make $415 million worldwide (yes, blockbuster status!), but $262 million of that came from international sales and only $152 million was domestic. It seems then, undebatably, that "The Proposal" is in fact the most successful summer rom-com of all time … in the US.

Personally, I didn’t think "Proposal" was anything special, but Touchstone’s marketing campaign (a.k.a. plastering Ryan Reynolds’ rockin’ bod virtually everywhere) seemed to pay off. Sandra Bullock’s return to romantic comedies after a three year hiatus also could have been the draw to make "Proposal" the impressive success that it was (though, I had no idea she was so well-loved). There also is the fact that it was the only big-name romantic comedy to come out of the summer. Regardless of the circumstances or the methods, "The Proposal" was a major hit.

And now it looks like CBS is trying to catch some of that winning formula -- though maybe drawing from the wrong parts. Variety reported this week that the network has picked up the new comedy "Open Books" from “Will & Grace” alumna Gail Lerner. The plot circles around the life of a book editor named June and her circle of friends. For those of you unfamiliar with the plot of “The Proposal,” Sandra Bullock was a successful editor at a New York publishing company. The question is: Will “Open Books” be a total flop without its own Ryan Reynolds?

What do you think about "Proposal" earning the #1 spot on the highest grossing rom com of all time?
