Jason Segel consults 'Handbook'

Joins comedy co-starring Jonah Hill, Jason Schwartzman

Jason Segel is attached to star alongside Jonah Hill and Jason Schwartzman in "The Adventurer's Handbook," a comedy Akiva Schaffer is directing for Universal.

Hill, Matt Spicer and Max Winkler wrote the script, about four childhood friends who are bored with the monotony of their lives and embark on a global adventure inspired by the stories of explorers detailed in Mick Conefrey's book "The Adventurer's Handbook: Life Lessons From History's Great Explorers."

Universal picked up the book rights as well as the script in February.

Segel would play a talented musician who never got his act together, becoming a backup piano player and an alcoholic; Hill plays an engineer, isolated from his family; Schwartzman is a spoiled and cowardly three-time Grammy winner.

The studio hopes to be in production by early next year.

Eric Fellner and Liza Chasin will produce for Working Title. Anthony Bregman also will be a producer.

Universal's Erik Baiers is overseeing the project for the studio.

Segel, repped by WME and Abrams Entertainment, worked with Hill in "Forgetting Sarah Marshall." The actor, who appears on "How I Met Your Mother," most recently starred in "I Love You, Man."
