If you've never heard of Winter the dolphin, get ready. She's about to be a movie star, reports the Huffington Post. Dolphin Tale, with Morgan Freeman and Ashley Judd, tells the true-life story of how Winter lost her tail in a crab trap at age 3 months. Doctors fitted her with a prosthetic tail so she could swim properly and, voila, a star was born. Winter now performs at the Clearwater Marine Aquarium, which has already seen a big jump in visitors and expects even more when the movie comes out in September.
