In this economy, who do you need to book in order to get your movie made? Forbes.com answers this question in its first look at the business side of Hollywood, for which it examined 1,400 actors to see whose billing could help guarantee the financial success of a film project. Will Smith topped the list, as his films have raked in a collective $5.2 billion. Johnny Depp, Leonardo DiCaprio, Angelina Jolie and Brad Pitt tied for second. Of the top 20, 16 actors have been nominated for Academy awards with a combined 69 nominations and 15 wins. Of the mere 27 ladies who made the list, Jolie was the only one to make the top ten.
