Star Wars News Net have posted this interesting article looking into some of the voice work for season four of Star Wars Rebels and wondering if Ian McDiarmid will be portraying the voice of the Emperor. As stated by SWNN in their piece, the voice work for the Emperor was already provided by Sam Witwer back in Season 2 as confirmed by Dave Filoni. Could this indicate McDiarmid will be replacing Witwer as the Emperor in the final season? Or was he recording dialogue for a different project altogether?
Long story short, six months ago, Warwick Davis was recording his lines for Star Wars Rebels Season 4 in London, and just a few days later, none other than Emperor Palpatine himself – Ian McDiarmid – did the same. This all sounds very alluring, but there is one big problem, Emperor Palpatine already appeared in Rebels Season 2, and was voiced by Sam Witwer.
