Isn't Jim Davis in JESSE JAMES MEETS FRANKENSTEIN'S DAUGHTER rather than BILLY THE KID VS. DRACULA?  Anyway, after both of those, on TV, there was a run of 10 episodes of GUNSMOKE, as well as his prominent role on DALLAS; movies: though his roles often weren't large, there were major movies like MONTE WALSH, RIO LOBO, BIG JAKE, THE HONKERS, BAD COMPANY, THE PARALLAX VIEW, THE CHOIRBOYS and COMES A HORSEMAN.
