Jason Segel, Jonah Hill and Jason Schwartzman are teaming up to star in “The Adventurer’s Handbook,” directed by SNL Digital Shorts/Lonely Island’s Akiva Schaffer.

The Adventurer’s Handbook follows four childhood friends, now grown men, who embark on an adventure inspired by Mick Conefrey’s book “The Adventurer’s Handbook: Life Lessons From History’s Great Explorers.”
