Peter Bretter has a problem. His girlfriend Sarah Marshall dumped him for a rock star named Aldous Snow, and now he wants to forget her. The plan is simple: fly to Hawaii, get a suite, and pretend the whole thing never happened. That plan falls apart the moment he arrives at the Turtle Bay Resort on Oahu and finds Sarah and Aldous already there. The comedy that follows is a mess of awkward encounters, bad timing, and a love triangle that never quite resolves itself the way you want it to.
Jason Segel wrote the script, and he plays Peter as a sad sack who can’t stop talking about his ex. Kristen Bell is Sarah, the woman who broke his heart, and Russell Brand is Aldous, the smarmy rock star who took her. Mila Kunis is Rachel Jansen, the hotel concierge who takes pity on Peter and becomes his unlikely new crush. Bill Hader plays Brian, Peter’s best friend, who suggested the trip in the first place. The supporting cast includes Jonah Hill, Liz Cackowski, Jack McBrayer, Maria Thayer, Paul Rudd, Jason Bateman, William Baldwin, and Kristen Wiig in an extended version as Prana the yoga instructor.

Peter’s Vacation Plan
The setup is classic rom-com territory. A man gets dumped, retreats to a tropical paradise, and meets someone new who makes him feel better. What makes this version work is Segel’s performance. He plays Peter as sincere and wounded, not bitter or vengeful. When he confesses to Rachel that his real dream is writing a Dracula puppet rock opera, it lands because we believe he means it.
The film spends a lot of time on Peter’s misery. He walks past happy couples, sees Sarah and Aldous together, and feels like the loneliest man on the island. Rachel tries to cheer him up, but the jokes about his job as a TV composer don’t always land. The movie leans on repetition — Peter keeps running into Sarah and Aldous, and he keeps getting caught in awkward situations — and that repetition is the point.
Rachel and the Cliff Jump
Rachel is the heart of the film. Kunis plays her with warmth and intelligence, and their scenes together are the best of the movie. When Peter performs a song from his Dracula opera at a bar, Rachel cheers him on. Later, on a hike, Rachel dares Peter to jump off a cliff into the ocean. He starts to jump, gets caught in vines, and hangs off the edge until Rachel prods him to let go. He lands safely in the water, and she kisses him.
These moments work because the film has built a bond between them. Peter is vulnerable, and Rachel is patient. Their chemistry is real, even if the plot keeps throwing obstacles in their way.
Aldous and the World Tour
The subplot involving Aldous and Sarah is less successful. Brand plays Aldous as a self-destructive rock star who is about to embark on an 18-month world tour. The news that Sarah’s TV show has been canceled adds to the tension, but the film doesn’t give us enough time with these characters to care about their relationship beyond the surface. When Aldous lets slip that he and Sarah started sleeping together a full year before she broke up with Peter, the revelation is supposed to sting. It doesn’t.
Brand is funny, but his character is more cartoonish than sympathetic. The film treats Aldous as a villain, and that simplifies a situation that could have been richer. Sarah is caught between Peter and Aldous, and the movie never fully explores why she chose one over the other.
The Suite Next Door
Peter’s room is needed by new occupants, so he is placed in the suite next to Sarah’s. This is where the film loses some of its momentum. Peter and Aldous run into each other while surfing, and Aldous’s confession about the year of sex is a turning point, but the film doesn’t know what to do with it. The resolution feels rushed, and the ending ties things up too neatly after a build-up that deserved more room to breathe.
The film is at its best when it focuses on Peter and Rachel. Their scenes have a quiet sweetness that the broader comedy often lacks. The cliff jump scene is a highlight, and the sequence where Peter performs at the bar is genuinely funny. But the middle section, where the film keeps circling back to Sarah and Aldous, drags. The jokes about Peter’s job as a TV composer start to repeat themselves, and the plot stalls while waiting for the final confrontation.
The Hawaii Setting
The Turtle Bay Resort on the North Shore of Oahu is a beautiful location, and the film captures it well. The shots of the beach, the ocean, and the resort grounds are a pleasure to look at. Filming began in April 2007, and the production budget was $30 million. Universal Pictures released the film in North American theaters on April 18, 2008, and it became a box-office hit, grossing $105 million.
The setting should have been a bigger part of the story. A vacation in Hawaii is supposed to be a reset button, a chance to start over. The film uses the location well visually, but it doesn’t use it dramatically. Peter spends most of his time inside the resort, and the island around him stays mostly off-screen.
A Mixed Verdict
“Forgetting Sarah Marshall” is a flawed but entertaining comedy. Segel’s writing and performance carry the film, and Kunis is excellent opposite him. The scenes between Peter and Rachel are the best the movie has to offer. But the subplot involving Sarah and Aldous is a weak link, and the film’s handling of the climax is rushed. The jokes about Peter’s job as a TV composer repeat themselves too often, and the film could have benefited from cutting a few minutes of filler.
| Element | Strengths | Weaknesses |
|---|---|---|
| Jason Segel’s performance | Sincere, committed | Some jokes about his job as a TV composer repeat themselves |
| Mila Kunis as Rachel | Warmth, intelligence | Scenes with her are limited by the plot’s structure |
| Russell Brand as Aldous | Funny, cartoonish | Character is simplified, not sympathetic |
| Cliff jump scene | Highlights the film’s emotional core | Comes too late in the story |
The film’s tagline is “You lose some, you get some.” That’s a fair description of what happens to Peter. He loses Sarah and gets Rachel, but the journey to get her is bumpy. The movie isn’t perfect, but it’s a solid entry in the genre. It’s a comedy that knows when to be serious, and a romance that knows when to be funny.
