Will Ferrell and Zach Galifianakis are set to star in an adaptation of Daniel Asa Rose's touching comic memoir “Larry's Kidney,” which will be directed by Richard Linklater, TheWrap has learned.

Scott Aversano will produce through his Aversano Films banner, and according to his bio on Focus Features’ official website for “That Awkward Moment,” production was expected to start in the spring. It remains unclear when cameras will begin rolling.

According to BookTheWriter.com, Ferrell will play author Daniel Asa Rose, who traveled to China with his black-sheep cousin Larry (Galifianakis) and his mail-order bride to save Larry's life by skirting the law and securing him a kidney transplant.

CAA is handling sales for the project, which balances comedy with life-and-death stakes. Another element of the project's appeal is its Chinese setting, as China is one of the fastest-growing moviegoing markets in the world.

Ferrell and Galifianakis previously shared the screen in WB's political comedy “The Campaign.”
