Dolphin Tale was a surprise hit in the theaters in 2011. Enough of a surprise for the film makers to create a sequel to the family-friendly film. Dolphin Tale 2 continues the narrative of Winter, the brave dolphin whose incredible rescue and recovery (complete with a groundbreaking prosthetic tail), made her a symbol of hope and perseverance to many.

The young star of the two films, Cozi Zuehlsdorff, had written a song, “Brave Souls.” In a new video recently released on YouTube, Cozi, who plays Hazel in both films, shares about how the Dolphin Tale movies and the dolphins Winter and Hope, inspired the words she penned.

Dolphin Tale 2 is scheduled to be released in theaters on Tuesday, September 9, 2014.
