Why did Bo Svenson play Bufford in part 2 and 3 instead of original Joe Don Baker?

Bo Svenson replaced Joe Don Baker as Buford Pusser in the sequels "Walking Tall Part 2" and "Walking Tall: Final Chapter" primarily due to Baker's prior commitments to other film projects. Svenson's portrayal brought a different interpretation to the character, aligning with the sequels' focus on Pusser's ongoing struggles against corruption and crime. The change also allowed the series to continue exploring Buford's story without Baker's involvement.
