"Nobody loved movies more. Passionate, loyal, generous, accomplished, noble, caring, heavily armed, creative, dare I say obsessive on occasion. A good man, a good friend, a wonderful partner, a loving son to his family," Jacks' producing partner Sean Daniel said in a Facebook message Monday.
Jacks and Daniel collaborated on "The Mummy" film franchise, as well as the movies "Dazed and Confused," "Tombstone," "A Simple Plan," "Michael," "The Hunted," "Down to Earth" and "The Jackal."
Funeral services are pending, Variety said.
