Cast Comparison: TV Series vs. 1997 Film
The 2025 series reimagines Grisham's novel with a fresh ensemble, while the 1997 film starring Matt Damon offered a compressed single-movie version of the same story.
| Aspect | 2025 TV Series | 1997 Film |
|---|---|---|
| Rudy Baylor | Milo Callaghan, developed across 10 episodes | Matt Damon, compressed feature-length arc |
| Leo Drummond | John Slattery as polished opposing counsel | Jon Voight in the same adversarial role |
| Format | Ongoing season structure with expanded subplots | Single courtroom drama with focused pacing |
