From "Money, Murder, and Dominick Dunne: A Life in Several Acts":
When Taylor was not creating problems, it was Burton’s turn. He housed a volatile temper, especially when drunk, which was often. During one early morning breakfast, Dominick burst into the actors’ caravan of trailers. He was frantic. “Where’s Helmut?” he asked. As usual, Helmut Berger was listening to the new hit single “Alone Again, Naturally,” which held some special significance for him. He played it endlessly. Keith Baxter continued reading Bleak House, and Henry Fonda went back to his hobby, painting miniatures.
“Helmut,” said Dominick, “you’ve got to come down! Immediately! We’re taking you to another hotel! Richard is on the way with a gun!”
Taylor’s daughter, Liza Todd, had made the mistake of developing a crush on Berger, and her adoptive father did not much like it. “Richard couldn’t bear the fact,” said Baxter.
Dominick threw Berger into a taxi and had him chauffeured down the mountain to the Hotel de la Poste.
After Dominick succeeded in saving Berger’s life, Burton did indeed arrive at the caravan of trailers. He carried no firearms but he was angry and, of course, he was drunk at ten in the morning.
“Where is he?” Burton screamed. “That queer, Helmut!”
Baxter explained that Berger had departed to another hotel. “He’s queer. Doesn’t it make your flesh crawl?” asked Burton.
“I’m queer,” said Baxter.
“But you’re Welsh!”
“You couldn’t have Liza in safer hands,” said Baxter. “Helmut’s wonderful with her.”
Liza Todd’s affection for Berger also disappointed Dominick, but for an entirely different reason. His daughter and Liza were about the same age, and he hoped they would “become chums,” said Baxter. It would have helped to solidify his friendship with Elizabeth Taylor. “But the two girls didn’t become friends.”
When Burton was not threatening Berger, he took to berating his wife. In one scene, the actors needed to improvise a game of bridge. Taylor got confused and asked, “Four of what? What am I supposed to be saying here?” She did not play bridge.
Burton, on the other hand, was an expert. “You stupid cow! Just show your big tits!” he yelled from behind the camera. During another altercation, Dominick watched as Burton called Taylor a “cunt” in front of her children.
