Director Sam Peckinpah was known for his genius at improvising great scenes on the set just before the cameras rolled. The four outlaws going to the final shoot-out in The Wild Bunch was a mere three lines in the script.

After the four outlaws getting their guns off the horses was shot, assistant director Cliff Coleman gave orders to move the camera & equipment to the shoot-out location. "What a minute, Cliff," Sam said, "I want to do a walk-thing."

 Cliff shook his head. "A walk-thing? What?" 

Sam mumbled something unintelligible and started lining up the four actors. Cliff started running around, setting up extras on the path to the shoot-out. Sam set up a bunch of men to act drunk and sing. 

Cliff said, "Nobody knew what Sam was going to do or what he wanted to do. But all of a sudden, the camera is rolling, the music is playing, these outlaw-guys start walking and people are saying, 'Wow, it's a real thing.' And it built and built, until it became that scene." The most famous walk in movie history. 

By the way: Peckinpah's director's credit placement will never be topped for its power. 1- Has a big star of the time. 2- Goes against Holden's type for the first time. 3- The scene suddenly reverses from good-guys to bad. 4 - Unusual freeze frame. 5- Powerful music stinger. 6- Powerful line of dialogue: "If they move, kill 'em." - See credit scene here: bit.ly/390Pxzq

Every artist can't get to the top of their artistic dreams like Pechinpah did, but we can all get a piece of it.

Example: On the a set of Forbidden Power, when the hero has the delusion of kissing three women at the same time, I planned for the scene to be silent.

Just before the camera rolled, I got an inspiration and said, "Wait a minute. I want to do a talk-thing, (purposely echoing Pechinpah) and quickly wrote up lines for each actress to say between kisses. 

And it became that scene; hopefully, the most famous triple-kissing scene in movie history.
