Somehow, we doubt movie reviews for Forgetting Sarah Marshall will even make a difference as far as the box office haul for this comedy goes.

Considering its pedigree and advanced hype, expect huge numbers.

Still, for those interested, the reviews have been mostly positive. Here's a look at a few for the film that opens on April 18...

- Personally, I can't remember the last time I laughed this hard at the movies... Without revealing the scene (because that would spoil the fun), this one has a shock value moment that is on par with Ben Stiller's classic "Franks and Beans" scene from [Something About Mary]. -- Reelz Channel

- One of those can't-miss romantic comedies in that there's some sweet, sensitive, insightful stuff for the ladies -- but there's also plenty of raunchy comedy for the boys. -- Cinematical

- Producer Judd Apatow looks to have scored another long-legged hit with Forgetting Sarah Marshall. -- Variety

- Writing and starring in Forgetting Sarah Marshall, Jason Segel gets emotionally naked. He bares his soul. Also, he lets us see his schlong. As Steve Martin said, comedy is not pretty. -- Kyle Smith
