Phoebe is an all-white thoroughbred cast as "Silver." She was discovered two years ago at the Valley View Acres horse farm in Woodstock as plans for the film got underway.
Phoebe is one of five horses used in various scenes and her specialty is jumping. Phoebe can leap four and a half feet.
She's seven years old, and trained at Arlington Park and Hawthorne, but apparently, she spooked the other horses because of her color.
