This show concerned the adventures of Cindy Prescott and her friend Willie Williams. Thunder, a black stallion who ran wild near the Prescott family's ranch, played a major part in their adventures. Whenever there was trouble of any kind, you could count on Thunder to ride in and save the day. The rest of the cast included Cindy's parents, Bill, a rancher, and Anne, a veterinarian. Cupcake, Willie's slow mule, also played a part in their adventures.
The show was created by the creators of another series involving a stallion, Fury, which originally aired from 1955 to 1960.
For about a month, the show was retitled "Super Horse, Starring Thunder" in hopes that it would improve the ratings. Thunder was aired in the middle slot during a 90 minute block of live action shows on NBC during the 1977 season. Unlike the two shows that surrounded it, Red Hand Gang and Search and Rescue: The Alpha Team, Thunder managed to stay on the air for a full season with all episodes aired.
From what I can tell, no complete episodes of the show are available through collectors. If anyone has episodes of this show, please send me an email.
