Personally, I don't think anyone, will rise to the star of Duke Wayne,
as far as I am concerned he is untouchable as far as longevity and popularity.
I too considered Harrison Ford, but lately he has become one dimensional,
and in my opinion, lately, has made some dreadful films,
sustainable only by falling back on Indiana Jones.
Too me there is only one pretender/ contender for the throne,
and that is the now 83 old Clint Eastwood.
