Director Judd Apatow is compiling his best celebrity interviews over the years for a new comedy book.

The Knocked Up filmmaker began recording his chats with his comedy idols and colleagues at the age of 16, when he hosted a high school radio show, and he has continued to document his interviews with the likes of Mel Brooks, Jerry Seinfeld, Roseanne Barr, Chris Rock, director Spike Jonze, and his Girls star Lena Dunham.

The discussions will now feature in a new book titled Sick in the Head, which will be published by executives at Random House.

Proceeds from the 2015 release will benefit 826La, a non-profit organisation which aims to teach young students the art of creative writing, according to The New York Times.

Apatow is no stranger to the publishing world - he previously put together I Found This Funny, a 2011 collection of humorous articles he had edited.
