In what is undoubtedly the biggest convention news so far, StarWars.com has announced that Ian McDiarmid will be attending Celebration VI in Orlando, FL, from August 23-26, 2012. CVI will mark the first U.S. Celebration appearance for McDiarmid, who played Palpatine in five of the six Star Wars films (counting his appearance on the Episode V DVD). He was present for the opening ceremonies of Celebration Europe in 2007. In addition to signing autographs, McDiarmid will "appear on stage in special behind-the-scenes programming."
McDiarmid joins Peter Mayhew, Carrie Fisher, and Jeremy Bulloch, along with other actors and behind-the-scenes talent, in a guest lineup that currently includes fifteen celebrities.
