Jason Segel is attached to star alongside Jonah Hill and Jason Schwartzman in The Adventurer's Handbook, a comedy about four childhood friends who are bored with the monotony of their lives and embark on a global adventure.

The Universal project is 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. Hill co-wrote the script with Matt Spicer and Max Winkler. Akiva Schaffer is directing.

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.

Segel worked with Hill in Forgetting Sarah Marshall, while Hill and Schwartman are currently in theaters with Funny People. Segel, who appears on CBS' How I Met Your Mother, most recently starred in I Love You, Man.
