Allison (Katherine Heigl) is a rising star in the entertainment television news business. Having just been promoted to an on-camera role, she is ready to party hearty and celebrate. Her sister, Debbie (Leslie Mann) is glad to help out, so the two of the them get dolled up and head for a trendy nightclub. Once there, Allison goes to the bar to buy some drinks but she has difficulty attracting the bartender's attention. Enter Ben (Seth Rogen). He helps Allison by arranging for her to get her beers without delay. Allsion is grateful and heads back to her table. Ben also returns to his circle of friends, where his pals chide him for not making more of a play for the obviously beautiful Allison. Bolstered by their suggestions, he approaches Allison again and they make a connection, albeit one that works better because of Allison's growing intoxication. They somehow end up spending the night together. But, in the morning, reality rears its ugly face. Allsion is a pretty lady with a great job and Ben is a consummate slacker with no ambitions or desire to change his present circumstances. Although they go their separate ways, fate throws them a curveball. Eight weeks later, Allsion learns that she is pregnant. Is there any possible future for Allison and Ben, that includes a baby? This is a very funny film, although the humor is as eyebrow-raising as it comes. The cast, quite large, is very nice, with Rogen doing a great job as the less-than-perfect suitor for Allison. Special mention should also be extended to Paul Rudd for his simply tremendous performance as Debbie's husband, a performance of humor and empathy. The whole production looks great, with well-picked costumes, scenery, and photography. Again, the script is the true champion here, as the story shines a bright, probing light on the realities of marriage, casual sex, money, and success. Although one would have to say, in the final analysis, that the film's conclusion is unrealistic, it is a very upbeat one, indeed. In essence, this is the brave new world of romantic comedy, told from the male perspective, as exhibited in such films as The 40 Year Old Virgin. As such, it is supremely funny and insightful but, if you prefer fun that is good and clean, you should pick another film, for this one treads into the limits of raunchiness.
