Jason Segel will star with Jonah Hill and Jason Schwartzman in The Adventurer's Handbook, a comedy that 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.
