Prince Eric in the Little Mermaid was voiced by Christopher Daniel Barnes, when he was only 16.
Yes, that’s correct. Eric, was voiced by Greg Brady (of the 1995 Brady Bunch movie).
Barnes has actually done a lot of voice over work. He is well known as the voice of Spider man in the 1994 animated series and also did the voice of Prince Charming in Cinderella II: Dreams Come True and Cinderella III: A Twist in Time.
