This is superb writing. Even the objections, responses, and judges' ruling are actually pretty spot on.
The actor Joe Stevens sorta steals this scene with his portrayal of "Lawyer Goudy".
Overall though, Jeff Bridges as "Rooster Cogburn" is one of my favorite characters in any movie ever.
I must really like Jeff Bridges as a law enforcement officer too, because his portrayal of "Marcus Hamilton" in Hell or High Water is also one of my favorite characters in any movie. (It's ironic that Bridges as "Cogburn" is always clowning on the Texas Ranger "LeBoeuf" in True Grit, then Bridges plays a Texas Ranger in Hell or High Water.)
This exchange in the courtroom scene is my favorite:
LAWYER GOUDY: I believe you testified to backed away from Aaron Wharton.
COGBURN: That's right.
GOUDY: Which direction were you going?
COGBURN: I always go backwards when I'm backin' up!
