Script review - "Butch Cassidy and the Sundance Kid" by William Goldman (re-reading)

 A script of set pieces ending in a revearsal gag. Sundance's intro. The fight with Logan ending in the kick in the balls. Meeting Etta the reveal that he knows her. Train robbery sequence. Bike riding musical number. Etta's departure. Final shoot out. Some catch phrases don't land - "I got vision and the rest of the world wears bifocals" etc. In hindsight, wonderful material - two friends, time running out, manage to repeat the past, a woman comes along for both to be in love with and she's part of the gang giving it female appeal, moving ending.
