Actress Zosia Mamet brought her horse to "The Flight Attendant" co-star Kaley Cuoco's house and ended up bringing one of Kaley's horses home instead.
"Kaley and I became very, very close shooting "The Flight Attendant," and I ended up living with her for part of our shooting. My husband was gone and she was living alone and we moved in together, and I brought my horse out to Los Angeles while we were shooting. And her mom ended up falling in love with my horse and I ended up falling in love with one of Kaley's horses, Herbie. So, we ended up swapping horses," says Zosia.
