First episode to be filmed at Warner Bros. studios in Burbank, Calif., after 11 years of being filmed on the Paramount lot. Both the Virginia City and Ponderosa sets were noticeably different from their long-familiar Paramount versions.
A completely new theme song, called "The Big Bonanza" and written by David Rose, was first used with this episode. This new theme would be used in seasons 12 and 13.
The last big building burned is Vienna's bar & casino from "Johnny Guitar". The arsonist apparently failed to grab the bust of Beethoven.
