James Gandolfini wasn’t jerking around on the set of "The Sopranos." The late actor — who tragically passed away in 2013 — reportedly threw a "tantrum" after he was ordered to film a masturbation scene for the groundbreaking series. According to the new book "Tinderbox: HBO’s Ruthless Pursuit of New Frontiers," the show’s writers penned a scene in which Gandolfini’s character, Tony Soprano, pleasured himself in a gas station bathroom.
