“When Mark Whitaker’s ‘Cosby: His Life and Times’ debuted on Sept. 16, 2014, it hit shelves with an enviable roster of A-listers singing the praises of the first major biography of the veteran comedian — as well as its subject,” reports Chris Gardner in The Hollywood Reporter. Gardner continues: “But as the shocking revelations continue to unspool due to now-unsealed depositions (in which Bill Cosby admits to obtaining quaaludes to seduce women in the 1970s for sexual purposes), those stars have pulled back on their endorsements.”

For example, Jerry Seinfeld’s blurb on the back of the books dust jacket says, “I know certain religions forbid idol worship. If anyone ever told me I had to stop idolizing Bill Cosby, I would say, ‘Sorry, but I’m out of this religion.’ So if you want to join the Religion of Cosby, as I did back in 1966, Mark Whitaker’s wonderful new book would be our Bible.”

The Hollywood Reporter says both Seinfeld and David Letterman have asked that their blurbs be removed from future editions of the book, which is published by Simon & Schuster.

The THR story notes: “Simon & Schuster spokesperson Cary Goldstein adds that as of Wednesday morning all of the endorsements have been removed from online retailers. It’s unclear if and when a paperback edition will be published, though it’s not expected that the endorsements will appear on any future editions of the book.”
