As its first big foray into the madness that is Comic-Con, D23 put on two panels and a member mixer. Starting off its first-ever SDCC panel, "Celebrating 90 Years of Mickey Mouse with D23: the Official Disney Fan Club," Walt Disney Archives Director Becky Cline, Official Voice of Mickey Mouse Bret Iwan, and Master Disney Animator Mark Henn took the audience members through a whirlwind tour of the iconic mouse's long and famed history.
