Mickey Rooney and Shirley Temple both auditioned for Our Gang/The Little Rascals but never joined Spanky and Company. But one of Mickey's sidekicks from the "Mickey McGuire" series did make it in to the Gang.
I just watched "It's A Mad Mad Mad Mad World" the other day, knowing he was the last surviving cast member. Then his number came up. Now they're all at the Big "W" in the sky.
Actually, the Shirley Temple story hasn't been confirmed. Both Shirley and her mother claimed it was false, but Hal Roach and Robert McGowan said otherwise. Ironic that we lost two of the most well-known former child performers within three months.
Incidentally, a few other "Our Gang" kids crossed over to "Mickey McGuire" at some point - Shirley Jean Rickert, Donald Haines, Norman "Chubby" Chaney (in one of his last film roles). Our Gang had a lot of rival series in its heyday. "McGuire" was not only the most popular rival, but also the longest-lasting one, and the only one to span both silent and sound films. Too bad it's hardly remembered today.
Yes, of the main cast of "Mad World", Mickey was the last to go. But a few of the supporting players are still with us - Barrie Chase, John Clarke, Nicholas Georgiade, Marvin Kaplan, Jerry Lewis, Stan Freberg, Carl Reiner.
