From the FAQ:
How much control over the film does Jack Chick have?
Chick Publications Inc. gave JR Ralls one stipulation: that the
film must include the message, ‘Story based on “Dark Dungeons” by Jack
T. Chick, LLC© 1984’. That message has been included, and otherwise, JR
Ralls has complete freedom of control over the Dark Dungeons film.
However, while he can make the movie however he pleases, he intends to
try his best to faithfully adapt the spirit and tone of the comic to the
screen given the limitations in transplanting fiction between two media
and in expanding a 22 panel comic into a film.
