"I'll be a suck-egg mule" was a Jack Elam line in "Rio Lobo" and also an Arthur Hunnicutt line in "Eldorado." Leigh Brackett scripted both movies.

Similarities abound with "Rio Bravo" too, the calm gunfighter (Wayne), the old geezer (Brennan, Elam, Hunnicutt), the gambler's widow (Dickinson, Holt, O'Neill)

"The Big Sleep" (the one with Humphrey Bogart) also has a parallel scene where the bad guys try to lure someone through a door (also scripted by Leigh Brackett and directed by Howard Hawks.) From Eddy Mars to Milt & Pedro.

Thanks for the reminder. Both of those are some of my all time John Wayne films to watch. But there are so many similarites that I get them confused.
