So, you're Warner Brothers, and you want to keep working with Leonardo DiCaprio, but how do you get him to stick around? Even though your last picture together - Clint Eastwood's 'J. Edgar' - wasn't exactly a hit, Leo's still one of the biggest names in the world. He did star in 'Titanic' and 'Inception.' So, to keep him happy, Warner Brothers bought him a book (how sweet!): Dennis Lahaine's 'Live By Night.'
