Arnold Schwarzenegger originally was to reprise the role of Conan back in 1997 in "Conan the Conqueror", which was rewritten as Kull the Conqueror (1997) starring Kevin Sorbo, when Arnold Schwarzenegger declined, due to commitment on Batman & Robin (1997).
This will be the first of the Arnold Schwarzenegger "Conan" movies not to feature Mako who had died in 2006.
Universal has now canceled the film.
