It’s full of funs, cringingly wacky scenarios, offbeat characters, comic dialogues, and laugh-filled experiences. Well, that’s all “Forgetting Sarah Marshall,” the American comedy film released today, is about.

“Forgetting Sarah Marshall,” written by Jason Segel and played by Segel, Kristen Bell, Russell Brand and Mila Kunis is not quite as funny as Knocked Up or Superbad, but it's still full of laughs.    

The movie is produced by Judd Apatow, who also produced the movies like, "Sarah Marshall," "40-Year-Old Virgin", "Knocked Up" and "Superbad”. Like the director’s previous directorial creations, “Forgetting Sarah Marshall” is movie for guys. The movie belongs to the genre usually pitched to a female audience with add sex elements, a touch of gross-out humor and - most important - a healthy dose of male vulnerability.

"Forgetting Sarah Marshall" is a smart comedy that trades on social embarrassment and shows love from the standpoint of male insecurity. It pictures the real life that’s what makes it a funny film.

The movie begins with a struggling musician Peter Bretter, played by Jason Segel, with a respectable job as the composer for a TV show. He has spent five years idolizing his girlfriend, television star Sarah Marshall, played by Kristen Bell. While writing a Muppet-type Dracula musical, he's the guy left holding her purse in paparazzi photos and accidentally omitted from acceptance award speeches. Things take a twist when she breaks up with him.

The moment of their breakup gives us one of the great comic tableaus of 2008: She's impeccably dressed, and he happens to be nude. Within a minute, he looks like a sobbing, quivering white whale, a blubbering heap of blubber.

Peter suddenly finds himself alone, after an unsuccessful bout of womanizing and an on-the-job nervous breakdown. He sees that not having Sarah may just ruin his life. He takes impulsive trip to Hawaii to clear his head, but there he comes across his worst nightmare and his humiliations continue. He finds Sarah and her narcissistic and tragically-hip, new British-rocker boyfriend, Aldous, played by Russell Brand, are staying at his hotel. He torments himself with the reality of Sarah's new life, but finds relief in flirting with Rachel, hotel clerk who takes pity on poor Peter. Rachel, played by Mila Kunis, is a beautiful resort employee whose laid-back approach tempts him to rejoin the world.

"Forgetting Sarah Marshall" features sex talk, sexual situations and male frontal nudity. The movie is rated R for its strong profanity, brief nudity, some sexual material. It will open in the UK on April 23, 2008.
