In 2009, British rock star Aldous Snow releases his new album and a titular single, "African Child", which is a commercial and critical failure.

Meanwhile, in Los Angeles, Aaron Green is a talent scout at Pinnacle Records, living with his girlfriend Daphne, who is completing a medical residency at a local hospital.

While performing live, Aldous is unable to remember the lyrics to "African Child", and replaces it with an old hit, "The Clap", to cheers from the audience.

On their flight to Los Angeles, Aaron learns that Aldous has become depressed, as he misses his son and has been alienated from his own father, Jonathan, for years.

Months later, Aldous, sober again, has returned to fame with a single produced by Aaron based on events from their night in Las Vegas.

Brand's friends Karl Theobald, Greg "Mr Gee" Sekweyama and Jamie Sives also appear in the film.

A week after the release of Forgetting Sarah Marshall, Universal Studios announced a new film, Get Him to the Greek, reuniting Jonah Hill and Russell Brand with writer/director Nicholas Stoller and producer Judd Apatow.

[4] Variety initially announced the project would focus on "fresh-out-of-college insurance adjuster (Hill) who is hired to accompany an out-of-control rock star (Brand) from London to a gig at L.A.'s Greek Theatre.

"[4] In July 2008, Brand mentioned that he would be reprising his Aldous Snow role from Forgetting Sarah Marshall, in a new film from Apatow in which the character was back on drugs.

[6][7] While Brand was backstage at the Paramount studio lot preparing to present the 2008 MTV Video Music Awards, he approached Christina Aguilera, Pink, and Katy Perry about filming cameos for Get Him to the Greek.

[3] Get Him to the Greek was released alongside Killers and Marmaduke, and in its opening weekend debuted second at the box office behind Shrek Forever After with $17.6 million.

The site's critical consensus reads, "Thanks to a suitably raunchy script and a pair of winning performances from Jonah Hill and Russell Brand, Get Him to the Greek is one of the year's funniest comedies.

[14] Roger Ebert of the Chicago Sun-Times gave the film three out of four stars, writing: "under the cover of slapstick, cheap laughs, raunchy humor, gross-out physical comedy and sheer exploitation, Get Him to the Greek also is fundamentally a sound movie.

Composer Lyle Workman, the film's producer Judd Apatow and Jason Segel, who starred in Forgetting Sarah Marshall, were credited for the lyrics to the soundtrack that features prominent musicians and artists, such as Jarvis Cocker, Mike Viola amongst others.
