Thursday, Kevin Carroll was in Waterbury at Hanger Clinic to inspire human amputees.
Many of them are now using the same kind of gel sleeve Carroll invented for the dolphin named Winter.
That sleeve helped Winter accept her prosthetic tail, to replace her real tail she lost due to fishing lines.
When Hollywood came knocking, Winter played herself, but Morgan Freeman played Carroll in the 2011 film "Dolphin Tale."
"When you're doing it, why not pick the best? The best actor in the world right there," Carroll said.
Carroll is vice president of prosthetics at Hanger Clinic. He visits with Winter often to check up on her prosthetic tail.
