We’ve all had our heart trampled on before by one person or another, but not too many can claim it’s happened while standing butt-naked in their living room. Such is the case in the latest movie from Judd Apatow’s production gang, “Forgetting Sarah Marshall.” Even if you are feeling the wear of Apatow in his recent movies, seeing this one may make you fall in love all over again.

“Forgetting Sarah Marshall” follows Peter (Jason Segel of CBS’s “How I Met Your Mother”), a music composer for a faux TV show (and blatant rip-off of “CSI: Miami”) which his girlfriend, Sarah Marshall (Kristen Bell of “Heroes” and “Veronica Mars”), is the star.

Just minutes into the movie Sarah breaks up with Peter. Depressed and in need of a break from work, Peter decides to go on a vacation to Hawaii, where he coincidentally meets Sarah and her new boyfriend, pretentious singer Aldous Snow. Before Peter can slip into despair, he is rescued by his hotel concierge, Rachel (Mila Kunis of “That 70’s Show”).

The movie starts strong as we watch Peter make himself a king size bowl of cereal and takes a shower before his soon-to-be-ex arrives. When she drops the bomb on him, the towel comes off, in true R-rated fashion.

From there, the movie goes into autopilot shortly after getting to Hawaii, not to say that it ever slows down or loses its charm. There’s not a whole lot on the side of gross-out humor, and even the language is fairly mild compared to other Apatow outings, but it still packs all the humor of his past hits in a new package.

“Sarah Marshall” is Segel’s first outing as a writer, and he does a solid job, but relies a bit too much on side characters like Peter’s surf instructor, the dinner host and a newly married couple for laughs. Even though they work for the most part, the movie would probably be better off without.

There’s a surprising amount of depth in the script that tries to make its main characters go as far away as possible from standard comedy cut-outs. The choice of having the film take place in Hawaii is made all the more effective since everywhere Peter goes, he’s surrounded by recently married couples on their honeymoon or walking past a reception in progress.

Joining the freshmen parade is first time director Nicholas Stoller who does a fairly good job, but his most notable “achievement” comes in the form of directing the boom mic operator. I counted at least six shots where you can clearly see the microphone hanging on the top of the screen. You’d think these things wouldn’t happen in a feature Hollywood film.

Segal works well in the lead role and is simultaneously charismatic and depressed. Kunis, Bell and Russel Brand, who plays the new boyfriend, are all equally as capable. Bell plays her character’s shifting moods with precision and always seems to be holding back, which makes the moments when her character lets go all the more effective.

In the end, the movie is just fun to watch. It drags on for a bit near the end, but the ending features a puppet theater performance that makes me want to see more. Anyone looking for a fun, enjoyable and entertaining movie should go see this movie, even if they do need to fire the guy holding boom mic.
