Brando behaved like a total child on the set; he addressed the director as “Miss Piggy,” he refused to wear pants (obligating the crew to shoot him from the waist up in all scenes) and even brought a note from his doctor, which claimed that the actor was allergic to Oz.
Allegedly, Oz then had to sit in a different room and give direction through Brando’s co-star Robert DeNiro in an ear piece.
During the filming of 1996’s The Island of Dr. Moreau, Brando refused to remove a makeshift ice bucket hat from his head and he also wore an earpiece for crew members to feed him lines while shooting.
