To Maria Bello the enigmatic Viggo Mortensen's still waters don't just run deep - they're rife with wildlife. "Viggo is obsessed with fish," says Bello, 38, of her A History of Violence co-star. No word, though, on if he loved the piscine-themed decor a secret interior designer created for him. Says Bello: "I'm happy to say, on the last day of shooting he walked into his trailer and saw a three-foot dead fish hanging from his chandelier. I'm not at liberty to say how it got there. But I'm very proud of it."
