This is one of the only flawless movies ever made...fave lines...
I loved EVERYTHING, it had humor, suspense, sadness, love, fear, action...everything. I memorized every single line.
No one can say that his phone call to his lover, Chris Sarandon wasn't the most heart-breaking, funny perfect dialogue EVER. AND it was ALL improv!!
I love when people ask this: favorite lines? There are so many...
I also have a review of Dog Day published on the Movies quotes and more website: http://www.moviequotesandmore.com/dog-day-afternoon-1975-movie-review/
