Wallace's second solo book, Yes Man was published in July 2005. In it, he describes how he spent six months "saying Yes where once would have said No", to make his life more interesting and positive. In this book he shows the tribulations and mischief that he got up to while he said yes to any question or proposal.
A film adaptation of Yes Man is in development with Warner Bros. and will star Jim Carrey . It is set to be released for the 19th December 2008.[3]
