At first it seemed that Star Wars Rebels would be the main source of tie-ins, though we now know that Saw Gererra from The Clone Wars will appear in the flesh as Forrest Whittaker’s character in Rogue One: A Star Wars Story as well.
More recently, the character received a mention in Rebels that helped to flesh out his history between The Clone Wars and Rogue One a bit more.
Since The Clone Wars was announced as being canon, many fans wondered when ties to the animated series would show up in the other Star Wars properties.
One of the few things outside of the six films to remain canon was Star Wars: The Clone Wars, the animated series that was intended to fill in the gap between Attack of the Clones and Revenge of the Sith.
