Fan CastingThe Dark Tower: The Gunslinger (2004)

As Roland travels across the desert in search of the man in black, whom he knows as Walter, he encounters a farmer named Brown and his raven, Zoltan. Roland spends the night there and recalls his time spent in Tull, a small town Roland passed through not long before meeting them. The man in black had also stayed in the town; he brought a dead man stricken by addiction to the opiate-like "devil grass" back to life and left a trap for Roland. Roland meets the leader of the local church, who reveals to him that the man in black impregnated her with a demon. She turns the entire town against Roland, who is forced to kill everyone. When he awakens the morning after telling Brown this story, his mule is dead, forcing him to proceed on foot.
