 Originally, the script had a major role for Lee J. Cobb (qv)s  character of "Lieutenant Kinderman" from the first film, but upon  his death the entire film was reworked. The script for "The Heretic"  apparently bore no resemblance to William Peter Blattys "Legion,"  which was later made into "Exorcist III" and featured "Lieutenant  Kinderman" (then played by George C. Scott) in a starring role.
