Viggo Mortensen rides back in ‘Hidalgo’

It’s not often an actor buys his co-star. But then again, Viggo Mortensen isn’t your average actor. And come to think of it, the co-star isn’t some hot young filly — it’s a real horse. “I just fell in love with him [on the set of ‘Hidalgo’],” Mortensen says. “He doesn’t live with me [in Venice, Calif.]. He stays at a friend’s house, and I go over to ride him as much as I can.”
