Winter was rescued in 2005 after losing her tail in a crab trap. An 11-year old boy who befriended her at the aquarium rallied friends and family to save Winter and convinced a doctor to create a prosthetic attachment to restore the dolphin's ability to swim. Winter played herself in the movie.
"Dolphin Tale" generated a solid $72 million at the U.S. box office in 2011 through Warner Bros. and another $23 million overseas. The 3D film was produced by Alcon toppers Andrew Kosove and Broderick Johnson along with marketing president Richard Ingber.
