[Brando took to calling Oz "Miss Piggy" (a reference to Oz's voiceover work on the Muppets), insisting that he be given his lines (which he typically refused to learn) by Robert Deniro through an earpiece, with Oz sending suggestions in from another room. And, to ensure that the camera wouldn't stray too low and capture his "godfather of bellies," Brando waltzed around the set -- without any pants.]
[During the production of Burn! (1969), director Gillo Pontecorvo began carrying a loaded gun, which he threatened to use if Brando continued to ignore his instructions.]
