Star Wars: The Clone Wars has had several great guest stars over the years known for iconic roles in other popular genre franchises, including George Takei, Simon Pegg and Katee Sackhoff. But for the first time, a Doctor is coming to the series, as none other than David Tennant appears on this coming Saturday’s “A Test of Strength.”
The episode continues the story arc begun last week, as a group of young Jedi set out to build their first lightsabers. The former Doctor Who star will voice Huyang, a droid who is a crucial part of this journey.
