The Hollywood Reporter's been doing a great job with their annual Roundtable video series, posting fascinating in depth discussions with some of this year's top screenwriters, actors and directors and cinematographers. For their Producers Roundtable, THR sat down with David Heyman ("Gravity"), Charles Roven ("American Hustle"), Mark Wahlberg, Pam Williams ("Lee Daniels' The Butler"), Michael De Luca ("Captain Phillips") and Dede Gardner ("12 Years a Slave") to talk about the ups and downs of moviemaking on a grand scale. Highlights include Roven talking about the personal toll the death of Heath Ledger took on the making of "The Dark Knight," and Wahlberg revealing how he almost fired his agent over losing "Fifty Shades of Grey" in a bidding war.
