Robert Redford fluffed one of his lines getting a word wrong and Dustin, like a total improv pro, caught the ball and ran with it. Great that they left that in.
The charge between them is palpable throughout, right from “I don't mind what you did; I mind the way you did it.”
Speaking of fluffed lines, I noticed to my amazement from the news clip that Nixon fluffed his, in taking the oath. In repeating the line "...to protect, preserve and defend the constitution..." he adds an 'and' between protect and preserve, which definitely isn't in the script. I've never seen it remarked on, and even googling didn't produce hits. I thought I must have misheard, but no, it's there alright - from about the
one minute mark, for anyone who's interested.
Reminded me of when Neil Armstrong famously fluffed the first line spoken on the moon. He'd meant to say "That's one small step for a man, one giant leap for mankind" which makes sense, not "small step for man, one giant leap for mankind" which doesn't, given that 'man' without an 'a' and 'mankind' are absolutely synonymous.
I suppose very few people notice/care about such things, but I find them interesting.
