The new Star Wars trilogy is underway, but as Star Wars: The Force Awakens easily showed, there are still plenty of ties to the original trilogy.
Frank Ozs Yoda was briefly heard in Star Wars: The Force Awakens as one of the many voices in Reys Force vision after touching Luke Skywalkers lightsaber.
Along with the seventh live action Star Wars movie, Oz recently reprised Yoda in two episodes of the animated series Star Wars Rebels, the first time hed done so since Revenge of the Sith (Tom Kane voiced him in Star Wars: The Clone Wars).
Thats assuming, of course, that Yodas voice wont simply be heard from the Force, like what happened in Star Wars: The Force Awakens.
