20 Behind-the-Scenes Secrets of Lord of the Rings
Bill the Pony Was Sometimes Two Men in a Pony Costume
Samwise Gamgee was a loyal friend, and he also had a loyal pony. The hobbit brought Bill the pony along on the first part of his adventure with the fellowship. Before they enter Moria, Aragorn has Sam turn Bill around. In the scenes where Bill is featured, though, he wasn’t always an actual pony. Instead, he was sometimes two men inside a pretty convincing pony costume.
The costume was apparently only used on rough terrain that wouldn’t be appropriate for an actual pony. A couple of times, the two men in the suit got too far apart and stretched the faux horse unnaturally. I’m sure that was fun to watch.
