Vernon Wells, he has played some villains in Commando as Bennett or more known for playing Ransik in power rangers time force, or homicidal biker Wez in Mad Max 2
also some roles in weird science, innerspace
now 73 years old, also being australian isn't a problem since we had Holly Valance, Jason Donovan before, and even Judge Craig is from Australia
i think he would be a affordable signing for BBC, also not a z-lister, his more recent work has been for the horror movie genre
but anyway this is my suggestion, who do you guys want as veteran actor/actress signing of this year's line up and what do you think of my celeb suggestion
