Anthony Daniels Quote: (from SiriusXM CV Interview 2010.08)

"I was wearing it (the 3po costume) about nine months ago for a project which will become clear in time."

Was originally thinking Star Tours 2. But there were reports of that filming in May of 2009. So maybe something for the blu-ray or maybe a SW Celebration DVD extra. All speculation on my parts.

Well the new Currys Christmas TV ad campaign features 3P0 & R2 so this could be what he was referring to ?
