Robert Duvall plays Frank Childers (Karl's father) in Sling Blade, not Vaughan Cunningham (who is played by John Ritter). Regarding improvisation: Duvall has confirmed that director Billy Bob Thornton used a "no rehearsal" method and shot the scene in no more than two takes to ensure authenticity. While some sources describe the scene as "entirely improvised," the specific line "I ain't got no boy" appears in script transcripts, suggesting the performance and reaction were the primary improvised elements within a structured scene.
The scene featuring Robert Duvall as Karl Childers' abusive father, Vaughan Cunningham, is widely believed to contain a significant degree of improvisation, specifically from Duvall, though direct quotes confirming all of his dialogue as unscripted are rare.
