All of these editions were subsequently re-recorded in 1997 with Frank Muller as the narrator for continuity. Muller narrates the fourth book in the series, The Dark Tower IV: Wizard and Glass. Stephen King selected Muller as his voice for all audio narrations at this time. Frank Muller suffered a catastrophic brain injury in a motorcycle accident in 2001. The narration task then fell to George Guidall, who recorded the final three books in the series in quick succession in 2003 and 2004. George Guidall was also called upon to re-record The Dark Tower: The Gunslinger, the first book in the series, in 2003, as the author made significant changes to that story to better match what came later.
