If you want to get stuck on previous roles, then Star Wars looks like this -
Frankenstein’s Monster (in a black suit and voiced by Lt. Lothar Zogg/Dr. Lou Rush) chases down Princess Lorna’s ship. Two droids escape with the stolen plan and end up with Corey Andrews (one of the more prolific bit parts he had). He chases the droids into the desert where they find Prince Faisal. After learning of his father and the force, and the death of his aunt and uncle. Corey takes Faisal to Mos Eisley where they hire Bob Falfa to take them to Alderaan. Meanwhile, Frankenstein’s Monster has taken Princess Lorna to the Death Star to be interrogated. Grand Moff Van Helsing is determined to destroy the rebellion.

You can’t worry about what people have done before, only whether they can pull of the role they are hired to play. Star Wars has had a lot of luck in that area.
